Precision is over the maximum defined for this asset.

Hello

I’m tring in the Binance Future’s testnet and I got an error precision every time… I don’t understand how to fix it.

    let price = await GetLastPrice();    
    let stepSize = global.filters[pair].stepSize; //pair = BTCUSDT
    let precision = stepSize.toString().split(".")[1].length || 0;
    let amount = (positionSizeInUsdt / price); //positionSizeInUsdt = 10000
    amount = binance.roundStep(amount, stepSize);
    console.log("Buy MARKET " + pair + " quantity: " + amount.toFixed(precision)+ " - stepSize: " + stepSize + " - precision: " + precision + " at: " + price);
    let buyOrder = await binance.futuresMarketBuy(pair, amount.toFixed(precision), {newOrderRespType: 'RESULT'});
    console.log(buyOrder);

And I got this error:

Buy MARKET BTCUSDT quantity: 0.268118 - stepSize: 0.00000100 - precision: 8 at: 37296.94000000 [Object: null prototype] { code: -1111, msg: ‘Precision is over the maximum defined for this asset.’ }

What is wrong with my code?

Thanks!

I also struggled with this problem and I figured out that for futures the precision is smaller than for spot trading. E.g. for BTCUSDT it’s 3 but you can check in the application for the specific pair (just try to buy in futures and below the scroll it will show the amount where you can figure out the precision).
