One second slippage, when the stop loss is hit, the spread will return to normal.

Every time it slips and hits stop loss. Without any news, the spread increased more than 200 pips in one second, and then returned to normal after hit the set stop loss order. This has happened several times. After I reported it, the platform said it was market behavior and would not solve it at all! In total, I have lost more than 7,000 US dollars! Black platform！
