CS Binance, the loss caused by forced liquidation is three times my original loss. I set stop-loss and take-profit orders, but they didn’t execute and instead liquidated my position.

I first asked customer service why my stop-loss didn’t execute, and the response was: the mark price is the trigger price, and the stop-loss price is the latest price.

I then asked about the differences and components between the latest price and the mark price, and customer service replied: the latest price is the transaction price of the last executed trade, while the mark price is based on a series of data. The latest price is determined by the price of the last executed trade; is there any trickery involved in that last trade, or is there potential for arbitrage? Looking at the composition of the mark price, MXC and ZhiMa have a relatively large weight, while Binance has a very small weight. Is there a possibility of collusion between ZhiMa and MXC, these two garbage exchanges, to set prices together?

Finally, I inquired again about the disclosure of forced liquidation fee income? Customer service was vague, and I truly suspect how much excessive profit Binance has made from this mechanism. They always claim that the forced liquidation fees are taken from the public and used for the public, yet it is a complete black box. I really don't understand how I benefit from the forced liquidation fees I pay? Also, who is the designer of this mechanism? Even Honor of Kings can disclose their planners; why can’t you? Is this the number one decentralized exchange? @Yi He
