Can SET still go up after facing selling pressure in the afternoon?

The Thai market has been quite volatile lately. It has been moving up and down sharply for the past two or three days. Today, it opened strong in the morning but was pushed down in the afternoon, closing around 1396. $ATOM also seems to have been affected. How do you feel if you are trading? Personally, I still think that if it doesn't break the key support level, it should be able to go a little further, but we also need to be careful about profit-taking pressure that might follow. Does anyone have any other graph perspectives or factors to add? Feel free to share.
