Here is the log from my program:

Latest position symbol NAIL filled orders.
8/3/2020 7:29:46 PM: 75f2b966-f3c9-4f5d-8b40-36f6a78ed20f: FilledAtUtc: 8/3/2020 7:19:12 PM, FilledAt: 43.31 (Filled Market 23 Buy)
NAIL: AverageEntryPrice: $43.31, UnrealizedProfitLossPercent: -0.2770722696836758, Quantity: 23
Attempting to place limit sell order for NAIL for quantity: 23 at price 43.19 (Place time: 8/3/2020 7:29:46 PM).
Exception: Alpaca.Markets.RestClientErrorException: insufficient qty available for order (requested: 23, available: 0)

As can be seen above, the buy order was filled successfully at 8/3/2020 7:19:12 PM (UTC) for a quantity of 23. The _tradingClient.GetPositionAsync(symbol) API call correctly reports the quantity as 23. However when the limit order is placed at 8/3/2020 7:29:46 PM (UTC) for the same quantity, the API reports that the available quantity is 0.

What is going on?

Hi,
I’ve seen this happen when you have another opened order for the same amount on the same position (e.g you used a bracket order, and then tried to close the position manually without cancelling the stop_loos / take_profit orders)

make sure you don’t have any other orders, and then try close your position.
