I opened 4 short positions at 4460 in the morning using 160u with 120x leverage, several times hitting the stop-loss at 4885 and 4886, and forced liquidation at 4887.78. I managed to hold on and sold at 3880.

Accidentally opened 41 after drinking, just one step away from returning to 0, the worst order I've done recently, left 1 after making 40 in the evening, fell at the last moment. The last one didn't come out when I woke up in the morning. Walked away when the profits retraced. With small funds, there's no way to adhere to 2% risk control, profits and losses stem from the same source, just don't play too big.
