Sometimes I really can't understand this logic. After opening a position, just leave it there, too lazy to even check the allocation ratio, and end up opening orders randomly everywhere. In the end, one careless move and it blows up. What happens after a margin call? Whether it's the market's fault or the platform's fault, they refuse to admit their own responsibility. This kind of mentality is too common in trading markets, and in the end, it's your own principal that suffers.
