binance-derivatives-trading-usds-futures ORDER_TRADE_UPDATE missing Activation Price

[nkoik1337]

Hi,

Looks like in the user data stream the ORDER_TRADE_UPDATE event comes with missing value on AP field (activation price).

From the docs:
https://developers.binance.com/docs/derivatives/usds-margined-futures/user-data-streams/Event-Order-Update
"AP":"7476.89", // Activation Price, only puhed with TRAILING_STOP_MARKET order

When created by TRAILING_STOP_MARKET order a MARKET order is created/filled, user data stream receives the following:

class OrderTradeUpdate {
	E: 1769537771039
	T: 1769537771039
	oLowerCase: class OrderTradeUpdateO {
		sLowerCase: LINKUSDT
		cLowerCase: H6APrOW0INUgqqAUWvbq5f
		S: SELL
		oLowerCase: MARKET
		fLowerCase: GTC
		qLowerCase: 6.91
		pLowerCase: 0
		ap: 0
		sp: 11.911
		xLowerCase: NEW
		X: NEW
		iLowerCase: 47380466423
		lLowerCase: 0
		zLowerCase: 0
		L: 0
		N: BNFCR
		nLowerCase: 0
		T: 1769537771039
		tLowerCase: 0
		bLowerCase: 0
		aLowerCase: 82.42248
		mLowerCase: false
		R: true
		wt: MARK_PRICE
		ot: TRAILING_STOP_MARKET
		ps: LONG
		cp: false
		AP: 0
		cr: 0
		pP: false
		si: 4000000466303765
		ss: -1
		rp: 0
		V: EXPIRE_MAKER
		pm: NONE
		gtd: 0
		er: 0
	}
}

The field 'AP' and related field 'cr' are always 0 with 'ot: TRAILING_STOP_MARKET'. Usually they are 'null', but when initialized with the right order type, it's just 0.
There is no other way to identify the order (created by an algo order) without the activation price, so this field is critical. Please help.
