Weak career move

Hi,

I recently switched jobs from a US bank to a Quant HF. I was clearly underpaid in this position, so much so my bank offered over $500k for me to stay (2x increase from my previous comp). I had quite a lot of responsibilities for my XP level (5yo) but I was a bit tired of this management and decided to leave instead.

Problem is, I have absolutely 0 responsibilities in my new job, micro-managing management, they don't trust me. Clearly they mislead me during the interview and baited me with a great career, though the initial comp would not be crazy (300k). So far, it's been a pretty poor experience and I start to think I should have taken the counter and switch after bonus day as it becomes clear my new firm doesn't plan on making me grow, these guys just wanted a quick and easy way to get my strategies in.

I have enough strategies that I could run a profitable book somewhere I have no doubt of this. But I have no way of proving how good my strategies were performing. 

Did this happen to anyone else? I am a bit tired of firms BSing their way during interviews, they don't want candidates to lie but they have no trouble doing it themselves. Should I stick to the firm for a while, should I try to move immediately? Should I just try to negociate a book somewhere?

It's pretty depressing to see my career half-destroyed by this move and I'm trying to get back on my feet. Any advice?
