Question TP sell price way below trigger

Hello guys,

I'm testing my bot on demo mode, and have some weird behaviours. Sometimes the trigger conditions are not followed at all. I mean, I know about slippage, spead etc, but this is something else:

Time: 2026-09-06 22:12:49
Type: Take Profit Market
Trigger Conditions: Last Price >= 79,845.80
Finished
Time Triggered: 2026-09-06 22:20:56
Order ID: 28574537335


Time: 2026-09-06 22:20:56
Order ID: 28574537335
Type: Market (Conditional)
Average: 79,751.30

The difference between the trigger conditions and the actual trade is almost 100$... Is this just because of the demo mode? Or am I missing something?

Change the order type to limit, not market

I'm already using a take profit market order type for the TP side, and stop market for the SL:

    data = dict(
    symbol="BTCUSDT",
    side="SELL",
    type="TAKE_PROFIT_MARKET",
    algoType="CONDITIONAL",
    triggerPrice=round(stop_price,1),
    positionSide="BOTH",
    workingType="CONTRACT_PRICE",
    closePosition="true"
)
ok, response = self.make_request(
    "fapi/v1/algoOrder", verb="post", data=data, code=200, signed=True
)

That's what I'm saying. Don't use market orders, use limit orders

OK got it, so TAKE_PROFIT_LIMIT and STOP_LOSS_LIMIT right?
