Only this way you can be sure that the strategy you had developed is really working.
I was looking for a strategy that will work on any timeframe and therefore will account for any amount of liquidity I might require. found it.
Need more liquidity - switch timeframe. that's it. that's not a secret to all.
Each timeframe obides and lives by its own specific rules. One needs to know the rules in order to be able to operate efficiently in a chosen timeframe. (offtopic)
)execution will play a big role I guess, but I am only planing to trade big on 15 most liquid NAZ stocks
