Quote from mcurto:
The AM membership is 1400 to lease versus the GIM which is 900 (nitro had them flipped around). I couldn't exactly tell you how much is saved, it all depends on how much size you are trading. If you are actively scalping or position trading every day more than a couple trades, it would probably be worth it. Furthermore, you will most likely get commission caps from your clearing firm if you are trading actively as a member.
