I was entering market orders of 500 or 1000 lots a time. I made sure to go below what I assumed would be the 'limit' in a real live account.
To add, I would start with a few contract and build up margin using buying power.
I don't even know where to begin on this...
Let's start with the screenshot here...

So last price on that GC contract was 1646. So the sim engine assumes you were in at that price.
Current bid is 2002, current ask is 2095. 2 orders for 2002, 4 orders for 2095.
Sure, great! If you actually were in that contract long at 1646, you could fill two lots at 2002 and be happy as a clam! 350+ points of profit is a lot of money in GC.
But...Yer not going to get a 500 lot trade at that price because, well, the bid at that price is for 2 contracts. So you will get 2 lots filled. Now you have 498 lots swinging in the breeze.
It is really irrelevant though, because if you have enough capital in your trading account to be able to open a 500 lot order in GC (or CL), then you should just buy QQQ, sit back, and enjoy the ph3T l3Wtz over time.
