Quote from riskfreetrading:
Guys:
A bit of an honest opinion. If cumulative delta is worth something why would the insiders (exchanges, market makers, etc) sell it?
On the other hand, I hope you know that the order flow is worth something and is sold by brokers. It is not sold to everyone, but to the insiders/market makerts. Now that is worth something for sure! A bit of a hint to you!
So, I am sorry to say that delta is worthless at best, and can even be harmful, except to the sellers of data such as the data provider championed by AMT (I wonder why he would do it, and also why he is maintaining this thread). Do not be a sucker.
Cheers
