Once you have determined the trend, you need to choose a direction to place your order. Remember these two sentences below:

1. Only trade in one direction

2. In an uptrend, look for support to go long; in a downtrend, look for resistance to go short.

Never think about trying to profit from both sides; if you want to go long and short, the final probability is that you will profit from neither side. You only need to know what the current trend is: in an uptrend, go long; in a downtrend, go short, and just follow the trend to place your orders.

Note: Determine the level of operation; the higher the level, the more stable it is. Choose at least the 4-hour or daily chart. From my calculations, generally, using ema21 is most suitable for the daily chart. In the daily trend, ema21 will be a good support point.
