You are over-complicating scalping by using a bunch of half-useless tools in trading view. You should not build your strategy on these indicators, at one point they simply will not work as it should and you will lose money. Build a scalping strategy at levels. Levels are the most reliable indicator of entering trades on the chart.
Scalping is most effective, productive and profitable for bull trend. If you do scalping trades with a coin that has a temp mini bear time, you will get losses.
Scalping or other trading methods, traders have to exit the market before the new cycle comes. If you are too slow and don't exit before the time, your temp profit from scalping will be stolen by Mr. Market. It is bad to blame that scalping method is bad because of your bad decision (don't exit).
