LOL I did a google search for AON thinking it was a company only to quickly determine that you meant All or None - just goes to show you how easy it is to misinterpret what someone says even in writing.
I dont think that AON or minimum shares works very well - my experience is they don't get filled, and like you said, you miss the purchase, but that is limited experience
Now as far as commissions, I almost dropped dead to find out my Schwab commission per order, which was already a low 6.95, will drop to 4.95 on Friday, AND they take you to a page where they show the competition prices and Fidelity is also now listed at 4.95. Well I checked my transactions for the last couple days in my Fidelity 401K and lo and behold, my commissions were 4.95. Now that is friggin competitive. I was paying 7.95 in Fidelity up to now (Ive had no choice since its a 401K with my employer and they allow penny stocks like DPW which is flat out crazy but I aint complainin)
Anyway I was the (lucky) low buyer of DPW at the lows for the day just about filling my entire order. Jump in mon, the downside is strictly limited, I'm dead sure of that much, how long it takes is an entirely different question I don't have visibility into. Granted, the lows of 40 cents back in July will never be seen again, that ship has long sailed, and so while this breaks my rule of NOT buying AFTER something has hit a (major) bottom and ALREADY rallied to some degree, at least it's still not that far from THE bottom compared to the lifetime of this stock when the company was not being managed properly, or even the recent spikes over a buck. And, I really like the action I see in all the 8-Ks.
