well, I differ in that way that I wouldn't buy at all anymore. If I missed a run, so be it. Time for another pennystock. However, I have more luck then 1/1000. Mostly I do succeed buying at the bid, especially when I see it bounces a lot, like here in ffgo.
And farmost, A company that proved itself and displays enough trust in the future, yes, I would buy immediatly at the ask. Not with OTC pennies though. I just flip them & keep the profit to have a possible (but most unlikely) run.
This way I almost never lose money with these pennystocks.
