First, do you have enough trading time? If you mean that you have enough trading time, then you can do a small cycle.
Second, if you want to make a big cycle, it depends on your capital. You said that if the capital is small, you can't make a big cycle, because if the big cycle fluctuates slightly, small accounts may break out.
Third, look at your trading system. If the trading system you design is a small cycle trading system, then you have to make a small cycle. If the trading system you design is a big cycle, you have to make a big cycle. In short, it should conform to your trading system.
