We are observing a three-wave recovery in the making, away from February lows, which can be labeled as blue wave B. That said, we can see first and second wave A) and B) completed, so current upward movement from 2648 level can be part of wave C), which can face limited upside and resistance around the 2876 level, where both former swing high and the upper channel line can offer resistance.
