Because there is no consistent way, the statistical results are of little value to how to guide the transaction. If you are unlucky, it is easy to lose money continuously. The more transactions, the greater the loss until it is unbearable.
If there is a trading system that trades in full accordance with the routine, how many opportunities will there be to open positions in line with the system? Sometimes there may be many such opportunities. Even if all positions are opened, as long as they conform to the rules of the trading system, there will not be too many or frequent problems. After all, there will be a period of time when trading opportunities are pitiful.
Therefore, the key point is whether to trade according to the system, not necessarily the less the better.
