Not a problem with access to enter trades, problem is they noticed the trade bust one day after it occured. I was arbing ICE vs NYMEX and it's rare that there is any arb available. Yesterday, there was and I got in for 30 ticks on RBOB vs RB. It's true that I was quite off market but not that much... I've done more without busts before.
The result is that my only trade left after bust was on RB and I lost 1500 $.
Fuck this but I'm glad it's only 1 lot.
