If you can make money on IBFX, you can double your profits just by going to an ECN where they have much more favorable spreads. That is one of the reason that most scalpers require low spreads to be profitable, and you won't find them on MT4 bucketshops. You are trying to exploit very tiny moves that can last a few seconds. And if you don't close out in that few seconds while you are in profit, then you lose that profit. That is the very nature of the term scalping. I think your strategy is not really a scalper. It's more of a volatility trap using multiple trades, perhaps using pyramiding logic / hedging.

And the funny thing about sizing grids, it will ultimately lead you to RR ratio. Sooner or later, you will see the power of just increasing the reward to risk ratio that will add to the bottom line because you eliminate the intermediate spread costs, so you are basically saying, I will hold on longer for a higher target. Then the evolution begins of trend following because that exactly what it is, following trend with large tp and small sl, which is the point I'm at, and been at for awhile now. Some might say I'm stuck here...which can be seens as a good thing or bad thing.

Anyways, that's about as much as I'm going to say because maybe my own limitations is preventing myself from finding a scalper. And I should not continue with this line of thinking and discourage you from your own quests for glory. As we are all just learning and adapting to the market.
