为什么我会遇到“保证金不足”的错误。在安装Binance API期货订单上？

Question

import { createRequire, runMain } from "module";
const require = createRequire(import.meta.url);

const Binance = require("node-binance-api");
const binance = new Binance().options({
  APIKEY: "<API-KEY>",
  APISECRET: "<API-SECRET>",
  useServerTime: true,
});

async function Trade(interval, { symbol, EnterAt, Type }) {
  try {
    if ((interval == "1h" || interval == "4h") & (Type == "SHORT")) {
      let response = await binance.futuresBalance();
      let pair = response.filter((el) => el.asset == "USDT");

      const leverage = 6;
      let quantity = Math.round(
        ((parseFloat(pair[0].availableBalance) * leverage) / EnterAt).toFixed(2)
      );

      let takeProfit = EnterAt - (EnterAt * 0.6) / 100;
      let stopMarket = EnterAt + (EnterAt * 1.1) / 100;

      // Adjust leverage
      let adjustLeverage = await binance.futuresLeverage(symbol, leverage);

      // Futures Market Sell
      let short = await binance.futuresMarketSell(symbol, quantity);

      // Set TAKE PROFIT
      let TP = await binance.futuresOrder("BUY", symbol, quantity, false, {
        type: "TAKE_PROFIT_MARKET",
        stopPrice: takeProfit.toFixed(2),
        closePosition: true,
      });
      // Set STOP LOSS
      let SL = await binance.futuresOrder("BUY", symbol, quantity, false, {
        type: "STOP_MARKET",
        workingType: "MARK_PRICE",
        stopPrice: stopMarket.toFixed(2),
        closePosition: true,
      });
      console.log("SHORT: ", short);
      console.log("TP: ", TP);
      console.log("SL: ", SL);
    } 
  } catch (error) {
    console.log(error.message);
  }
}

function wrapUpTrade(interval, { symbol, EnterAt }) {
  binance.useServerTime(() =>
    Trade(interval, { symbol: symbol, EnterAt: EnterAt })
  );
}
// wrapUpTrade("1h", { symbol: "XRPUSDT", shortAt: 0.774 });
export { wrapUpTrade };

该代码仅用于期货市场卖出（卖出短）。为什么我在下订单上的订单中遇到的差额不足，而我的钱包里有2.9美元？在利用（6倍）时，我将拥有（6 * $ 2.9 = $ 17.4），大于$ 4.5，但我仍然会遇到错误的错误。功能交易需要一些论点：

Interval: "4h" or "1h"
symbol: "PAIR/(USDT)" // BTCUSDT, ETHUSDT
EnterAt: It is used to calculate Stoploss and TakeProfit. The type is int.
Type: "SHORT", means futuresSell
