Prateek VSA works on any and every time frame. This is where the style of trading comes into picture. Although this might be against general consensus ,time frames like 1,3, and 5 minutes will whipsaw you all over the place unless these small time frames are used as strict entry/exit points which are based on Strength/Weakness in higher time frames.
This is the approach that i use while trading VSA/Wyckoff Methods
1.Assessment of Background is more important than anything else.
2.This will help you in understanding the trend of the market.
3.Once the trend is understood look for confirmation.
4.Once confirmation is seen try to find your place in the trend (entry point ) and then see if you belong in the trend (if the stop is too wide and makes you feel uncomfortable then do not enter).
5.Just before taking the position the final confirmation for an entry point should come from a higher time frame. If not then wait for a while.
