NTPC analysis.
Monthly: It is pretty much in a down trend with SZs being respected and DZs being busted on the way down. Recently it hit the DZ but hardly any buying power there which is evident from the fact that even before price could reach the next SZ from the DZ, price tanked back to the DZ which was now used up somewhat. So selling pressure on the HTF monthly!
Weekly: Here, Price was coming down and hit DZ which send price up to the two stacked SZs above, busted the first one but second one held and sent price down signalling seller insti(s) are pretty much dominant. Stacked levels (2 levels very very closed to each other or even touching each other. Sorry, I should have included this in the basic building block series! Will do soon!) In stacked levels, break of the first one is perfectly ok as long as the second or third one held! The DZ already had 2TB to it so pretty much depleted and river current on the downside.
Daily: On the daily, I can hardly call out any DZ, all compression below and SZs working like a charm! M/W/D all telling that selling insti(s) are clearly at the party!
Now with the W/M/D in view, let's take a look at LTF 15 min.
Notice where the 15 min zone is located with respect to the HTF Daily fresh SZ, right at its edge! So was it a good play to go long at a 15 min DZ? Not really! This makes it a lower probability trade when the HTFs are telling that Sellers (Instis) are dominant at the moment, and this was like going against them inside their bastion! Buying at 15 DZs was not a good idea but selling at good qualified 15 min SZ was! Its not that all DZ won't work in such scenarios, some will work, but going against the tide is always more stressful, so gauge the flow and go with the flow!
We all make mistakes which learning something in the initial stage, these were the trades I used to take as well, so don't worry! It's part of the learning curve. More you practice, spend time on this, more you will refine your reading skills.
