You can track these setups using Sensibull option platform.
i calculate the gann levels in the morning and use it as an guidance for my supports and res. stops and profits levels. but i generally carry and modify with the market dynamically. As I said earlier i am a very visual trader. i try to get inputs from market movements and modify my trades based on the sense I get. else I let the trades run to my set stops or targets.
for eg. if i sense a good move in one direction and I happen to be on the correct side I may carry the trade with trailing stops, whereas if I am on the wrong side I may exit even if the stops havent been hit.. of course there are times when this has not worked out, like i would have exited too early or unnecessarily covered, but largely it has been beneficial to me
