As we can see BANKNIFTY has tested its support multiple times now making it weaker hence to confirm the downtrend it had to sustain below 41600-41500 levels but at current scenario it looks like BANKNIFTY might show some upmove and also a trend line can be seen to which a breakout can be expected anytime sooner, for confirmation one must wait for BANKNIFTY to sustain above 43300 to which more like W pattern can also be witnessed
