I need someone to develop an automatically trading script by using binance api.
It should place limit-buy and limit-sell orders like this: for example the BNB/USDT price is $10 now, the script places a limit buy order like $8.5(the ammount is 5 BNBs) . when this order is completed, the script should place a sell limit order at $12 immediately(but only sell 4BNBs). And when this sell-limit order is completed, the script should place the $9 limit buy order again. buy 5,sell4,buy5,sell4...never stops.
Could someone write this script for me? there is no limits on which language you develop it. python, java, js, c, php etc are all right.
