I have 2 accounts. On one account I use 5 mnq on Qzeus London and NY and 2-3 MNQ on Qkronos 1 minutes (this one blew one account with different settings and on 5 minute). On the second account I use 10 MNQ with max 16 contracts 16 MNQ in case of a loser. I am using bulenox because I needed a NT platform prop firm which allows EAs in funded and cheap challenges, because I have only passed once and failed everything else manually trading. APEX is my favorite, but it only allows EAs during challenges, not funded.
