Ouch...sorry about that VP....
Flow method can be used for all timeframes till 15mins.......below that is a bit difficult.For 5mins and below,the attitude should not be that of Going with the Flow,but more of a Sniper Attack.You get your setup,you pounce,you make your gains,and then out,out,out.Get in again.Do it all over again.The Asish style.
And yes,it is applicable on anything so long as you can trade it.Cash,Futures,Commodities..........where it cannot be used is in low liquidity,scratchy charts.Have explained that somewhere in the last 10 posts.
For daytrades,2/5/10 min charts...........
All the best!
