How to use ETFs instead of Indexes to know how to trade that day

Most Traders use the indexes to try to understand whether they should buy long or sell short. However, the ETFs impact the index components prices not the other way around. Most traders do not realize that they should be studying the ETF of an index rather than the index to determine how to trade the next day. Also ETF trading can be highly lucrative. Using the chart layouts that I have designed to trade Dark Pool activity, HFT and Hedge Fund activity and Sell Side activity helps you understand who is on control of price for the ETF and thus is created the value changes of the indexes.
When you study the ETF rather than the index, you will find you have far more information in the chart, indicators and price changes.
