trade details for future bug?

• CCXT version: 1.84.75

It seems that there is some issue for future trade detail for some exchange as cost != price * amount and the trade details seems off.

kucoinfutures: price:29580.89, amount: 745 <- this seems very off, cost: 22037.76305 okx: ‘price’: 29474.0, ‘amount’: 10.0, ‘cost’: 2947.4 huobi: ‘price’: 29277.4, ‘amount’: 2364.0, <-- i think this got multiplied by 1000, ‘cost’: 69211.7736, mexc: ‘price’: 29444.5, ‘amount’: 319.0, ‘cost’: 939.27955 aax: ‘price’: 29717.53, ‘amount’: 1.0, ‘cost’: 29.71753, delta: ‘price’: 29420.0, ‘amount’: 100.0, ‘cost’: 3.3990482664853e-06,

@leastchaos the ts issue should be fixed in the most recent version of CCXT, please, let us know if you still have difficulties with it.

I see, thank you. I now see a mismatch on delta exchange
