Precision is over the maximum defined for this asset

[ciclanoio]

I'm running tests but I still haven't got it working, it's not clear to me the amount to be invested in the order and I get this error. Any advice is welcome.

{"code":-1111,"msg":"Precision is over the maximum defined for this asset."}

What market/assets are you trying to trade?

It's happen if you trade eth/usdt, btc/usdt or xrp. Bot just can't place exact amount order. In bot_functions.py change qty = 0.05 or 0.06 or 0.07 like this way.

im having the same issue, which line we should change exactly and what does it mean basically

[Nai-mul]

in bot_functions.py you need to change qty=qty * 0.99
to qty=qty * 0.98 or qty=qty * 0.97 or qty=qty * 0.96 like this way.

the bot are basically failed to calculate how much quantity need to place.

in bot_functions.py you can search buy Ctrl+f by this line qty=qty * 0.99 and then change it.

I think this is happening because floats aren't great at accuracy in some cases (vs decimals, more info here). What I suspect happens (unverified, just speculating) is the round_to_precision function in bot_functions.py uses string formatting to strip the position size down to 8 significant digits (if it was rounded instead, there's a chance it would round up and the order wouldn't go through as it's more than the wallet has), but then you see the qty figure gets cast as a float before being passed on to the Binance client - in the case of certain difficult-to-represent-in-binary numbers, this'll cause it to flip out and be some gigantic long fraction like 16.6999999999999999999999999) and then Binance rejects it.

However, turns out you can pass a string to Binance and it'll accept it - I removed the float(new_qty) casting on line 167 so it just returns the number as a string instead, and I haven't had precision issues since.

It works. Just return new_qty instead of float(new_qty).
