Today was a contradiction to your theory. I watch the ES and YM when trading the ER. The ER has been leading the ES for much of the past year. Today, percentage-wise it lagged all the other indices but buying the low at about 719 and you would have had a strong trending run to 726. There was little downturn during the move.
Quote from scalper21:
I was wondering if any of you take into account what ES is doing to make your ER2 calls. I scalp ER2. I would be flying blind if I was not watching the spread between ER2 and ES.
For example if you are looking to get long ER2 and it is the weaker index you probably are going to get stopped out all day. The chart might make it look all pretty, but if ES is up 7 points and ER2 is only up 4.5 points it can be a hard day to buy ER2.
I am not a fan of charts. I do not use them during the trading day. They make trading look to easy!!
