In the very big picture, SET INDEX is still in retracing phase. If 1350 is broken down, we will see around 1200-1265.
In the smaller time frame, it can bounce to reach 1430 first before broken down 1350. So, in case that it really come to 1430, if cannot break up or flow did not come in. It will be the time to sell and cut loss before anything happen.
For trading individual stocks, just follow your stop loss level.
