opening and closing an order

API Spot/Margin API
1

I check the operation of the api, the algorithm is as follows: create a buy order and after 1 second create a sell order. This does not work stably, I can get an error on the 20th cycle or on the 3rd (I attached the logs). How can I have insufficient balance with this kind of logic?

I wrote to the chat, but did not receive a response since yesterday, I tried to write to dev.binance.vision, but I was also banned there since yesterday. I wrote in telegram: “help, I cannot write to dev.binance.vision” and received the answer: “write to dev.binance.vision on this issue” WHAT ??? And I had to look for another account from which I just wrote.

disappointed with this attitude, not to mention the clumsy documentation, which in the end I have to debug on a real account losing on commissions. How do you think I should close a deal by / order / test, if I need to close the amount of purchased crypt, and in response I get an empty array? You say: “go to https://testnet.binancefuture.com/fapi/v1/ it is indicated in the documentation as a test one” and I was there, only it has little to do with the combat api.

When you do symbol=BTCUSDT&side=SELL&type=MARKET&quoteOrderQty=14.99626496, you’re using 14.99626496 USDT worthy of BTC to sell BTC, but you need to be aware that the market price is constantly changing, so if the price decreases a lot, 14.99626496I USDT is worthy more BTC than what you have available and hence the error message.
