Hello Raghav,
Scalping actually should be done in sideways market when market is going up/down by 2-3 points but with STT and taxes 2-3 points scalps are no longer profitable...one needs 8-10 points profits to make it profitable....
In the attached chart I have marked sone points where the moving average direction is down, market is trending down, identify a small NR5 or NR7 bar or inside bar, sell the low of this bar with high as a stop....cover 1/2 position once 2:1 reward /risk is achieved...then balance position trail the stop to high of successive lower bars.
Here the trick is to identify trending market and a small bar indicating a possible pause in the trend....chart shows a few locations, red line is short and blue line is stop. A pure R/R play really once you have trend in your favour...
Best wishes,
