Python Dash app that tracks whale activity in cryptocurrency markets.

crypto-whale-watching-app's Issues

Wrong order sizes listed on graph

Should be 30, 40, 50, ... 120, 130...

Or is this intentional to not clog the space up?

@pmaji also unrelated, but ladder_tooltip_screenshot.JPG and bubble_tooltip_screenshot.JPG should be updated to show the new info available in the tooltip (and I guess the readme as well).

Websocket empty?

Hi all,
I have been trying out the app and I think is awesome, although I am getting a lot of websocket empty messages. This is the same issue that @pmaji open in danpaquin/coinbasepro-python#361 but I think is specific to whale-watching-app hence I open it here. Taking a look at the code I think the problem is although the code is trying to use websockets, is still performing polling requests (for each websocket message) which are rate limited by CB. The line 25 in gdax_book is doing this:
res = self._client.get_product_order_book(self.product,level=3)

for each message that is received on the websocket.
CB docs mention this:
Level 3 is only recommended for users wishing to maintain a full real-time order book using the websocket stream. Abuse of Level 3 via polling will cause your access to be limited or blocked.

At the moment I only see one way of fixing this:
-Get the full order book ONCE (when app is launched) and store in database
-update it for each message we get on the websocket

Let me know your thoughts please, happy to help with the project.
Cheers

Errors appearing when hosting

Hi guys, the syncing stopping problem is still an issue. When looking at the logs I discovered that they often print errors for different graphs like this:

Make hover state stay up until you mouseout

Right now when you hover over a dot, the tooltip disappears before you have a chance to fully read what it says. It should stay up until you move the mouse off of it.

Hosting

Looking for long term and speedy options for hosting this. I tried Heroku to no avail. The present plan now is to move to AWS long-term, but I'm open to other suggestions in this thread.

Variable controls for ladder price-point whales

@theimo1221 you can see in my updated README that I have split our definition of whale into two types. There is a bit of a methodological blind spot that I identified though when it comes to what I called "ladder price-point whales", i.e. those that we mark with the linebar chart instead of the bubble. Namely, the problem is that we ALSO pick up on psychological modal points.

What I mean by this is that, for example, 10 ETH is a very popular volume amount. So is 5 ETH. If many people put orders for 10 ETH along the span of say pricepoints of $950 to $1000, our present methodology would flag this as a potential whale. That said, if we saw a bunch of orders for 10.0085 ETH spanning that same range of prices, THAT is more likely to be a whale, because it is a rarer volume number (and thus less likely to just be a psychological modal point that many people might pick).

It's very hard to control for this, but I think one way to do it might be to exclude from our ladder price-point whale-identification logic any span of orders that is obviously a popular order number (i.e. 10 / 5 / 1 / and maybe a few others). The problem is that this logic is a lot more based on assumptions than the single price-point whale identification logic, but we can make it a bit better I think (given the logic I laid out here). Let me know your thoughts.

Can't toggle/untoggle Freeze/Colorblind and...

With colorblind on, tooltips on ask side flash green/blue.

If Freeze is toggled, it would be great if the button changed to "Unfreeze"

Help wanted with web hosting of app

I installed at

http://whaledectector.com

Site missing CSS, shows no graph.

On console, i get error "No graphs loaded yet".

Any idea why it is not wokring ?

@pmaji

Problem with "unique" orders

Look at this comparision:

In the bottom current code, wich groups by price and then filters all less than 1% of Volume in Range.
In the top I first filter all orders < 1% of Volume in Range and then group by prize.

This results in much better data. e.g. the sell order at 0.083 (yellow) is 1 50 ETH order plus 5 additional orders (summed up to 6 ETH).
Top graph warns about a whale. Bottom graph say "Nah, it´s okay, there are 6 unique orders"

Wrote it as an issue to post picture.

App doesn't work any more

Doesn't plot any graph, doesn't load any data.

Edit: I see this is also mentioned in bugs #112 and #113

I tested both on Windows and Linux, same issue. Maybe related to danpaquin/coinbasepro-python#365 ?

Questions to explore further beyond the app

Given the treasure trove of data that we now are developing, as well the growing community of traders / coders that are involved in this project, I wanted to open an issue where people can periodically contribute questions that they want explored further.

My aim to open up a Python Notebook separate from this app in which we can dig into deeper (perhaps more long-form analytic questions) that this app or curiosity in general may create. Comment below with any hypotheses you want tested or theories you want explored, etc., and I will add them to the master list of topics to add to the exploratory Python Notebook that will be created.

List of subjects to investigate:

• Investigate temporal weekly trends (i.e. what really are GDAX's volume / volatility trends over the course of a week, and are these patterns predictable? Do things really go up Sat. night and come down Sunday morning?)
• Impact of holidays (if any) on trading patterns
• Is there a time-zone that dominates the volume?
• Are particularly time-zones more / less bearish / bullish than others?
• Is it true that eth price follows btc with a short but perceptible lag?
• Correlation between bot activity and price movement (i.e when bot trading is more prominent does that necessarily lead to a higher likelihood of upwards vs. downwards price swings)
• Correlation between more volume and price?
• Investigation of whether or not TA beats buy-and-hold and over what time span if at all?
• Portfolio performance question? Does holding the 20 lowest price coins vs. the 20 highest price coins yield a higher return over time?
• Are there any exchanges in particular that more often than not lead the market? (i.e. does an upswing on GDAX cause an upswing elsewhere?)
• Look in the data to first identify what seem like the same bot trading regularly, and then see what correlation there is to price swings.

Time Stamping - Alt Coin Buzz

You guys have a great tool here! I haven't seen any work lately. I'd like to promote you on my segments that I do on Alt Coin Buzz. It's a TA segment along with the news. Are you still working on this? If so can I promote, or would it be better to wait?

Also wondering if you guys are working on a time stamp for the trades to be included in the roll-over. Certainly would be helpful to see if the larger orders are set up to affect the price.

Thank you in advance!

Better plot coloring / market price visual

• show logic for margins specification and adding background color
• need to choose a better background / plot color (just picked one arbitrarily to show proof of concept)
• need to add horizontal line to show market price
• would love to be to selectively color the background such that above the market price is a very faint color of red and below market price is a very faint color of green (this comes after the horizontal line implementation)

Is there a way to grab the results and store in Variable or print in console

I wanted to see if its possible in order to grab the results from the graphs and store them in a variable i can use to perform other tasks for example i want to get the prices and total btc that is in the orderbook that a whale has placed when i run dash it prints everything to the console but i would like to print the data from the app or store them in a variable any way of doing this?

Few ideas and questions

• Add a link to the bottom of the page linking to the github
• Add a slider to adjust the refresh time
• Permit to add dynamically new charts, as we saw, the only thing to change is the eth-btc or eth-usd to get bch-usd etc... It shouldn't be too hard to re-use the code and let user add charts with a button
• If we could add new charts/pair add a save button and just save the config so we won't loose anything if we stop the app.
• Adjust the size of the circles size when zoomed in the graph, it's hard to see when you zoom on the small order!

Q.

• I was trying to find documentation regarding the column address you request in the code, what does it return ? In the description you said the app allow us to see if walls are from one person of few person right ? In the graph X axis is the price Y the order size, how can I see if the big red circle with a sell order size of 350 and at a price of 815 is only one whale or few others players ? I can only see a circle, what if a guy set a sell order at 815 for 200 and and another one at the same price for 150, how can I see these are two different person/order ?

Thanks!

How to run

Adding OKEX info in separate version / integrated version

So a fan / supporter reached out and mentioned that they were wondering if we could integrate OKEX into our present methodology. They had already written some python code to hit the OKEX websocket API, so some of the work has already been done for us!

See this link here for their first crack at some websocket code. I'm thinking how we might want to add this. At the moment, I'm thinking of maybe demo'ing a separate instance of the app dropping the coinbase api info and replacing it with OKEX info. If it works, we can then think of a solution that combines both--either via a menu option to select the exchange, etc.

I welcome any and all thoughts at how to proceed on this matter!

License

Is this open source and what is the license?

Adding visual call-outs for high order count vs. low order count

Taken from a reddit comment; should be able to do something like this:

"Can you put perhaps a thin black stroke around the circles that are controlled by say under 5 addresses and perhaps a thick one around 1 address? Also a small written text of the price really close would be great - hoovering the mouse and it going in less than 2 seconds is hard to keep track of when they’re moving. Thanks excellent tool."

app.py cannot work and got the error 'message': 'Failed to subscribe', 'reason': 'No channels provided'

Adding ETC

I was wondering if you plan on adding ETC to the app now that's ETC is listed on Coinbase Pro.

Bid limit is incorrect

This line incorrectly takes first_ask, as opposed to first_bid. Additionally, first_bid is never initialized.

BTC-GBP plot is messed up

See horizontal line & annotation: https://i.imgur.com/UQ6qyS2.png

Group by volume additionally

Had a nice and good discussion with Paul. We found many good and some little points.

Pull #41 did a lot of changes towards original goal of detecting whales and fake Resistances/ Supports.

Currrently we spot fakes by grouping price.
An additional approach would be grouping by volume (e.g. 50 orders of 1.53 ETH from $962.65 to $984.42.

At current state we thing adding a bar at the position of summed up volume with the bot beeing at the start and top beeing at the end of price range could be best.

Needed steps to do this:

• Calculate new dataset
• Grouping dataset
• adding go.bar or rectangle
• needs description in legend
  I guess go.bar won´t work cause we start at different y-levels

Order Book chart

Hello,

in my Opinion it would be nice to see the total size of order-book by a line in the background.
Due to the fact, we already have the data, it would be little problematic.

I just have the problem I´m not familiar with Plotty....

Thanks and Greets

Theimo

Edit:
Needed Tasks:

• Sum upp Data for graph
• Add code for Plotty

Rework legend

• Logscale
• Color Description
• Show/ Hide Buttons
• Filtering on low volume

No hover text on Plotly lines

As suggested here #31 (comment) it'd be great to have a hover text on Plotly lines ("ladder whales") as with the bubbles instead of annotations, but Plotly does not support that. A workaround might be https://stackoverflow.com/questions/46037897/line-hover-text-in-plotly/46039229#46039229

Adding Binance / Other Exchanges

An issue to collect data and tasks needed for adding binance

• Decrease Callback/ Load Amount to 1 in #40

• Analyze compatibility
  Needed changes in Data call?
  Needed changes in Data storage (Multiple times same pair e.g. "ETH-USD")

• Discuss form of presentation
  Original:Send all data to client, and hide/ show selection on clientside with js?
  Update: Sending all data should be no problem due to changes in #40
  Maybe rework show/ hide in the future, to show/ hide complete exchanges.

• Add Dropdown to select exchange
  Update Show/ Hide Button is much easier

• define format for get_data function
  Goal is to keep get_data modular for future.

• exclude api calls from get_data function

When we change this we should change #28 aswell

Thanks and Greets

Adding ETHBTC ratio

appv0.1.txt

Hi, I'm no way near a coder, just a sysadmin debugging perl/python/bash code sometimes. I was playing around to see if I was able to add the ethbtc chart, I think I got it.( Don't really understand the details, it's all copy pasta from your code ;) )

Feel free to take a look and adapt it if you want to merge in the code!

Thanks again for sharing!

Tooltips

Hi,

I really appreciate this tool and it's fantastic. The only thing really bugs me is that the tool tips when you hover over an order block disappears too fast without you getting a chance to digest the information. Is there any way you could possibly make an option to just always keep the hover tooltips on if for example you clicked the order block.

Thanks

Install erros - version conflicts

Trying to install with python 3.6.0 but got the following error. Modifying the version manually creates a lot more errors...

ERROR: Cannot install -r requirements.txt (line 3) and requests==2.21.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested requests==2.21.0
    cbpro 1.1.4 depends on requests==2.13.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

App looks like it's doing nothing on initial load

I've been wondering how to fix this myself but I don't know enough about these libraries to figure it out. When you load the app it looks like it's doing nothing for 10 seconds until it makes the first requests to the server to get the data.

It seems to be because of the interval being set to 10 seconds, it waits for the first 10 seconds to tick and then it loads the data. What would be better is if it loaded the graphs immediately on the page's first load and then updated them every 10 seconds, but I can't see how to do this from the library being used.

Add selection of Pairs

Hello team,

needed Tasks:

• Add Js function to hide/ shown specific graphs (solved in #40)
• Decrease Callbacks/ Load to one (as well included in #40)
• Choose Method of selection

Requirements

Since there are a couple of dependencies you should do a requirements file so people can install all the dependencies with pip. To create a requirements file all you need to do is setup a virtual env and only install the required python packages then do "pip freeze > requirements.txt". With that it will output all the names of the dependencies along with the version you were using.

Changing dark/ bright

Hello,

what do you guys think about changing current dark/ bright to an algorithm based color.

This way you could see a difference between 1, 4, 6 and 100 unique Orders.

Currently 1=4 and 6=100.

Additionally if we touch this, we should think about making it readable for people with red-green issue

Thanks and Greets

Theimo

Edit: Needed Tasks

• create a button that changes the color coding to something that red/green color-blind people can use
• implemented color based on unique orders in #37
• discuss continuous dark/ bright vs slider with border

Zoom is lost when graph refresh

it's all in the title, it would be nice to stop refreshing when zoomed in, or better refresh but keep the zoom as it is!

Error: MacOS: Found existing installation six 1.4.1

Hi,
I get this error on my MacOS 10.13.3 (17D102) when running the installation and hence cannot continue:

Found existing installation: six 1.4.1
DEPRECATION: Uninstalling a distutils installed project (six) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.

Adding "total price" worth to ladder whale orders

Now with #66 merged, hovering over a bubble shows the total price of the order/s. I tried to add the same to the ladder whale orders, and if I play with a simple test dataframe it works, but when I try with app.py, I get an error on:

    vol_grp_bid = vol_grp_bid[
        ((vol_grp_bid[TBL_VOLUME] >= minVolume) & (vol_grp_bid['count'] >= 2.0) & (vol_grp_bid['count'] < 70.0))]

for some reason. Could someone with more experience implement this?
