You should not be setting your ladder steps at round numbers,
Pish. I used to place my orders 'just off' from round numbers. Yes, they executed earlier. No, I found no evidence to suggest they executed more often than round number orders would have. Even if there were some minimal incremental benefit, that is outweighed by the PITA factor. At least for me.
I had to look up PITA, just to make sure that I understood the context of your apparent manufactured exasperation.
More simply put. We can just agree to disagree on this angle.... even though I had thought that you had previously agreed on this technique..
Yeah, I did. But my experience taught me that -- at least in my case -- I saw perhaps zero benefit, and more headache.
