Trend is forming a similar structure to bullish ascending triangle and moving in a channel. One can look for bullish setup. Right now, entering at the current levels would be risky because short-term trend looks still bearish. If you blindly enter, then trent can become your enemy. :p
Around 632 seems firm support, it might be difficult to break those levels.
For such simple and highly accurate setups see my other charts. Thank you.
