Note: Binance has strict rules about the minimum trade amount and the significant digits of prices and amounts.

For example, you cannot issue a 0.0015 order for BTC-ETH, but you can issue a 0.002 order because Binance limits ETH orders at 3 significant digits. The limit varies with each pair. BlueBot automatically takes care of verifying the number’s accuracy is correct and it takes care of rounding when needed.
