Was it possible to partially hedge YM contracts with ES contracts at IB? One - one ratio they correlate highly... maybe not a perfect hedge, but darn lose. When CME goes down I look to offset ES or ER with YM contracts first, or S&P futures in the pit after that. BTW... I personally use brokers with floor access I can reach on the phone. Just curious why one wouldn't cross stranded YM trade with ES on a close correlated hedge.
