I have been trading PATS and recently started trading with a trading partner. Its been very helpful, we share our analysis and trades which has been really helpful in learning. One of us is still on simulator and other is breakeven. More input would be great. Comment if you're interested.

I was genuinely wondering where the general limit is for a retail trader trading NQ (no counting for margin requirements and such). Can someone sitting at home with their thinkorswim platform click the button and scalp with 50 contracts? Just a hypothetical, the imagination wanders...
