Hi question not issue.

Hi, currently there is not. What would you expect if this?

Hi, well when i send a quantity in a buy order, the quantity has to meet the LOT_SIZE filter on binance, or i get the following error, -1013 "Filter failure: LOT_SIZE"
unless i am wrong , the quantity has to meet the requirements below.
I think other versions of this type of library (ccxt for example) have a function to convert your quantity to one that is divisible by "stepSize" .

This is from the Binance API documentation:

LOT_SIZE
The LOT_SIZE filter defines the quantity (aka "lots" in auction terms) rules for a symbol. There are 3 parts:

minQty defines the minimum quantity/icebergQty allowed.
maxQty defines the maximum quantity/icebergQty allowed.
stepSize defines the intervals that a quantity/icebergQty can be increased/decreased by.

In order to pass the lot size, the following must be true for quantity/icebergQty:
quantity >= minQty
quantity <= maxQty
(quantity-minQty) % stepSize == 0
/exchangeInfo format:

{
"filterType": "LOT_SIZE",
"minQty": "0.00100000",
"maxQty": "100000.00000000",
"stepSize": "0.00100000"
}

I could add toggle-able functionality like this, where the library automatically complies to the ExchangeInfo filter rules, and return an error or auto adjust the parameters to comply. Would that be helpful to you?

That would be awesome thank you 👍 Sent from Yahoo Mail for iPhone On Wednesday, January 24, 2018, 09:56, Jan Korf <[email protected]> wrote: I could add toggle-able functionality like this, where the library automatically complies to the ExchangeInfo filter rules, and return an error or auto adjust the parameters to comply.

Hi, I've just pushed a new version in which BinanceClient contains a TradeRulesBehaviour. Setting this to ThrowError will return an error if the order doesn't comply. Setting it to AutoComply automatically complies the parameters to the rules (min/max price and quantity, and the step/tick sizes).

For manual usage there are also Clamp functions in the BinanceHelpers class which you can use to comply to the trading rules.

After having to google what Patreon was, I´ve come to the conclusion that sadly I do not
