Take profit or stop loss expires without closing main position

[chibexme]

Hi Everyone, am having some weird scenarios, through API I place LIMIT or MARKET order with STOP_MARKET and TAKE_PROFIT_MARKET for futures trading, every thing works well most times but randomly STOP_MARKET or TAKE_PROFIT_MARKET order expires without closing the main order.

Please, what could be the possible cause(s) of this behavior?

An order may be expired for different reasons. What time in force are you using?

I used as below:

GTC - for LIMIT and MARKET orders
GTE_GTC - for TAKE_PROFIT_MARKET and STOP_MARKET orders

If you are trying to replicate the Take Profit / Stop Loss OCO feature on futures, I suggest having a look at this thread.

How to implement OTOCO(TP/SL) orders using API

I don’t use developer tools to dynamically insert the parameters into the call to the api with python. I only used it as a reference to see what the parameters should be when making a trade that included a TP/SL. If you look at my first post, you will see the parameters I used for each call. Creating a trade that includes a TP/SL cannot be done with one call to the api - as we have already established. It needs three calls, right? So, I used developer to see how Binance were doing it. I then c…

The Futures API does not inherently support OCO orders, they must be handled by the client instead.

I have experienced the same issue recently. The answers so far seem to be focused on explaining that the Futures API does not support OCO linking of market orders and associated TP/SL orders. I am clear on what you were saying with your question. My code handles any straggling TP/SL orders when I close a position but with GTE_GTC, I have found that the Binance system seems to close them automatically despite statements that it doesn’t support OCO via the API.

However, your issue is identical to mine. My position remains open (my algo hasn’t triggered a close of position) and my SL GTE_GTC order expires or is cancelled and it doesn’t show up on my websocket monitor. Too many days have passed for me to look the old orders up but I know they were placed as “New” with GTE_GTC as I log from my client websocket monitor to a database. I also have a periodic (hourly) refresh to pull open positions and orders to a dashboard and I spotted my SL order gone with my position still open.

I take onboard tantialex’s comment “An order may be expired for different reasons” but I am at a loss to understand what would have caused the order to expire while the position remains open. This was a liquidation protection stoploss order and having SL orders just go expired is a real worry.

Did you ever get to the bottom of this issue?
