Hi Team,
Python 3.8. API.
Really appreciate any feedback you can provide; Here’s my scenario. Its actaully driving me nuts.
Here’s the sequence of events I am trying to achieve, its classic stuff
- Place BUY Limit order to buy 10 tokens say at 1 USD each.
1A) Wait for confirmation (execution) that I actually own 10 tokens at 1 USD each - Issue SELL Limit order to sell 10 tokens at 1.05 each.
The issue is this. I am getting a confirmation (“FILLED”) after a wait/while loop from 1/1a). So now I KNOW i own 10 tokens.
Time to sell;
When I attempt to sell , I am getting “INSUFFICIENT ASSETS” . The BUY limit order has executed (I can see it in Binance APP). NOW I am in a position to sell the same asset at buy price +1.5%, say. Fails eveytime with insufficient FUNDS. I can SEE it in my wallet though. I can also see it in trade/order history. But BINANCE API won’t let me sell it. Do I need to invert the symbol pairs? I mean, buy FTM/BUSD, then sell BUSD/FTM

Code looks like this;
// buy/sell code
def place_buy_limit_order(client, symbol_pair: str, qty: int, prc: float):
order = client.order_limit_buy(
symbol = symbol_pair,
quantity = qty,
price = prc)
print("PLACING BUY TRADE: Pair:", symbol_pair , "BUYING qty: ", qty, ", ExecutedQty: ", order["executedQty"], ", BUY Price: ", prc, ", Quantity Ordered: ", qty)
print(order["executedQty"])
print(order["status"])
print(order)
executed_qty = float(order["executedQty"])
status = order["status"]
orderId = order['orderId']
return executed_qty, status, orderId
def place_sell_limit_order(client, symbol_pair: str, qty: int, prc: float):
order = client.order_limit_sell(
symbol = symbol_pair,
quantity = qty,
price = prc)
print("PLACING SELL TRADE: Pair:", symbol_pair , "SELLING qty: ", qty, ", ExecutedQty: ", order["executedQty"], ", SELL Price: ", prc, ", Quantity Ordered: ", qty)
print(order["status"])
print(order)
executed_qty = float(order["executedQty"])
status = order["status"]
orderId = order['orderId']
return executed_qty, status, orderId
----------------------- THIS IS BUY/SELL LOOP that fails consistently with LIMIT SELL ORDER (Insufficient funds)
