Some important thing to keep in mind to become a profitable trader-
* Trade with the flow. It is easier to pull off a trade in the direction of market so mark your highs and lows and use them as confluence with whatever strategy you are using.
* If it is too obvious, avoid using that plan or wait so you can get an upper hand. Because if it is obious every one trades the same plan and it might end up in liquidity hunt.
* Don't rely on old S/R lines becase they get weaker as liquidity is absorbed each time price goes there.
* Try to focus more on right side than left while charting.
