If your bad trade is, say "long at 26, exit at 7" then you've lost -19 points. Assuming you paid a 3-point spread on the entry, this means that if you invert the trade, it becomes short at 23. Pay the spread on the exit and it becomes "short at 23, exit at 10", so your gain is +13 points - not quite the opposite of minus 19.
If you could take home +13 instead of -19, would you care about abandoning the 6?
Similarly a short trade that's say, "short 63 exit 84" becomes "long 66 exit 81" in the same way, again assuming a 3-point spread. -21 becomes +15.
If you could take home +15 instead of losing -21, would you care about leaving 6 behind?
As Swing Traders, we don't care about spreads. We work in a realm of big movements and whether the spread is 0 or 16, we just don't care, because if we are smart Swing Traders, then we have already accounted for the average trade cost and built that into our Revenue Model - which we "accept" as good enough for Production Trading. So, 0 spread or 20 spread, we've already agreed in our own minds that it "works" for us.
Spreads don't bother me. Having my intermediary close my successful trades without my direct and explicit instructions to do so - or - waking up in the morning and finding out that several new positions have been opened without my tacit agreement and direct execution - now - THAT bothers me.
Spreads are not the problem. Bucket Shops and Rigged Server Side Trade Management DLL's and Add-on Modules that you never see as the Customer/Trader, now that's the problem.
All I need is for my positions to move. I don't care what direction they move in, just MOVE. If they are moving, I'm winning, regardless of the spread. Heck, in my case, spreads could be 40 pips and I'm still winning. For that matter, 75 pips, and I'm still going to win a very high percentage of the time, even if it takes me all month to do it.
Focus not on the spread. Instead, focus on ways to position your capital in front of the "next" wave of price action.
I am reminded of that movie called:
Stand And Deliver. Remember that one? Remember when the Calculus instructor, Mr.
Jaime A. Escalante told his students to
"...Just Fill the hole..." And,
....A negative times a negative equals a positive.....say it.....A negative times a negative equals a positive.
There is so much truth to this in trading the Forex. Nature abhors a vacuum.

...but have been testing a simple mechanical signal for intraday trading in recent weeks. Without any "filters" the system has lost -406 points over the course of 113 trades...
Its not the magnitude of the aggregate loses that matters alone. It is the magnitude, frequency and cyclic pattern of the losses that matter in synergy. You have to look at more than just pips over time. You have to also include a study of pips over time per cycle and isolate magnitudes that cover profit requirements, so that you don't end up with an aggregate -2.41 in the end.
If I inverted the system, and had to subtract 6 pips from each trade as in the examples above, I'd still be on to a loser to the tune of around -2.41 pips per trade...
Not if you signals that failed
very well with enough magnitude, the right frequency and in cyclical patterns that lend themselves to "routine" probabilities.
"...Just Fill the hole..."
....A negative times a negative equals a positive.....say it again.....A negative times a negative equals a positive.
