Futures trading not possible: APIError(code=-4164): Order's notional must be no smaller than 5.0

Question

I'm trying to create a new futures order with a little money in order to test my bot but gives me errors:

order=client.futures_create_order(symbol=sym,side=f'{signal}',type='MARKET',positionSide= "LONG",quantity=str(coinQuantity),leverage=10)

error=binance.exceptions.BinanceAPIException: APIError(code=-4164): Order's notional must be no smaller than 5.0 (unless you choose reduce only) I really don't know what notional means in here and what is restricting me,I did this change:

order=client.futures_create_order(symbol=sym,side=f'{signal}',type='MARKET',positionSide= "LONG",quantity=str(coinQuantity),leverage=10,reduceOnly='true')

but also this time it gives me this error:binance.exceptions.BinanceAPIException: APIError(code=-1106): Parameter 'reduceOnly' sent when not required. coinQuantity is 0.001 and symbol is 'ETHUSDT'. python 3.7.9

Answer 1

The new update from binance will not let trades in futures to be made using api less than 5 dollars(and that was what notional was meant!) so I needed to make my trade a bit bigger than 5 dollars like 5.01. and positionSide(and reduceOnly) parameter was absolutely unnecessary ,since it is only needed for hedge mood. The new update.
