Dear Raviji,
I am posting sample SBI chart...although volume footprints are not exactly the same...but rest of details are on line...
When we anticipate a crucial support zone then we need to wait for price to test the same...on testing either aggressive ones need to enter with small SL, or for conservatives need to wait till price gives us few clues...
Now, whether this support zone is prominent or not, it is to be analyzed first...Remember one thing for every effort(volume) we need to see result(price) is coming or not...
Observe, weekly chart, the support zone tested by outside bearish bar with high volumes...now if its a weak we need to see follow up...but see prices traded inside this outside bar for two weeks...
Now, on daily chart, observe in Feb prices trading below Jan month lows, so bearish pressure still intact...But the high volume down bars which tested support zone, is not witnessing follow up selling to clear the zone...so it was clear price has another plan...
In base observe, up bars are with above average volumes and bigger spread..this is sign of accumulation process...
While analysing charts, always try to see what price is doing...clearing previous months/week high/low gives signs of strength/weakness...this is all need to read in addition to volume...Price if sustaining below previous months low, and then comes up, it will challenge previous months high...if it overcomes, then bull give their signature that we now have strength...
