Your chart looks so similar to exactly what I was doing just a month ago. I don't know how, but I kept catching the tops, and going long, or catching the bottoms, and going short (ha... and guys say you cant catch a top or bottom... I was good at it.. just trading in the wrong direction! LOL). They are at least legit SLA trades, and I can see how the entry is exactly one point away from the crest or trough.
Its a bummer that it sometimes doesn't work, and I know my fear of money loss is what kept me from taking the next trade for example which would work and make up for the loss.
Anyway, I just wanted to point out that just because it doesn't work, its important to not think that you are trading badly. If you are following the SLA rules, which it looks like you are doing, then you're trading well, even if the trade didn't work! If you stop taking the SLA trades, this is where you might not be able to let the power of statistics work for you. And of course after two losses in a row its important to stop and wait for price to go somewhere else. But I just wanted to tell you that I think you are doing well because you are following rules.
Also, I saw for myself that after price moved against me right away, I probably could have exited sooner. When you watch a tick chart or even if you have a 15 second chart up, I was amazed at how after a short for example I had lots of higher lows and my exit could have been made much sooner.
I think when Db says that you should give price room, this is contingent on where you got in. If its right above a range and price dips back into the range, then the breakout trade from the range is clearly not working, so no point in waiting around. If anything, I think given the first long for example, it looks like a mini range to me, so waiting for the solid retracement after price leaves the range is probably best... which I can only say in hindsight of course though. But this long is based on the retracement happening within the range, so its not as good. Giving price room is best once price is trending, but today was an ugly day where it was just stuck in little ranges for most of the morning.
Anyway, I clearly don't know what I'm talking about since I haven't been able to come up with a consistent plan yet, but just reading what you wrote and looking at your chart made me think of me... so I wanted to say I fully understand what you are doing! LOL
