I’m not sure why it is, but that has happened to me. From past experience, my regular limit orders have filled, often a portion at a time over several minutes, when my all or none orders went unfilled. So I don’t use all or none orders anymore.
If you place an order, of any kind, and it doesn’t fill, just edit your order and increase your bid by a few percent and it will fill.
I never understood diddling over a few percentage points on a bid when the goal is to sell that stock in the future for a gain of hundreds or thousands of percentage points. — I’ll amend that. I can see the utility of trying to squeeze every last nickel out of a short term transaction. But if one is truly long and strong, and is looking to sell down the road at many multiples of the current ask price, why refrain from buying shares if the cost is only a few points over one’s initial bid?
I’ll bet dollars to donuts that some folks who wouldn’t increase their bid of $.0830 when the ask was $.0840 will be buyers at $.15 or more.
