I'm starting to think that success in trading is more about who gets the best deal on commissions as opposed to anything else.
Well, I qualify as an expert on micro scalping and I think most of us would say that trading for 4-5 PIP losses is getting close to the micro scalping category. There are several things that you should look for in a broker:
1) a "proportional" commission based upon lot size, not a fixed amount per-trade. Real ECN type operations like Dukascopy or LMAX give you that but you're in the U.S. and you can't use them. I'm thinking you're using Interactive Brokers? From the perspective of commission, you might look elsewhere depending whether you're using their lower tier FX or higher tier what used to be called Idealpro.
2) a broker with an API which enables you to enter on a pull-back, or use limit orders to make the market come to you. This gives you price advantage on the pullback. Somebody can write you a simple client using the API which can give you assistance in 2 areas: a) entry to the trades, and b) management of the ongoing trades, such as "trailing stop" approaches.
3) use multiple limits to enter, staggered to improve your volume weighted cost basis forcing the market to come to your price, rather than taking the less advantageous price which the static market is offering you...
Any techniques which you can reasonably use to make the market "come to you", improve your pricing, and/or lower commissions will improve the situation. But having such a tight stop loss fundamentally will erode your account, so perhaps you can "widen" the stop situation to reduce your stop-outs, or change your trade management techniques.
When you're asking the market to "come to you" using Limit orders, you need to be perfectly satisfied if it does not come to you, and so you simply don't enter the market. This is a big deal in reducing price adversity stop-outs because you are "grabbing" the market on a pullback, thus stacking some odds in your favor.
Just a few ideas,
