Mind over Markets will get you tuned into a
view of how to model the markets behaviour by modelling it as an auction. It is independent of the timeframe you will eventually trade. Check out John Grady's NoBS Trading if you are interested in trading purely off DOM and FT71 if you want a more holistic view of how to trade auction market theory. I find FT71 more in line with how I trade and he posts up some interesting views which demonstrate a depth of understanding that transcends my exposure to ES.
I trade by looking at 3 things with emphasis shifting on what I am looking at dependent on circumstamces:
1) T&S - this tells me what the order flow is doing
2) DOM - this tells me about the available liquidity that is being consumed
3) Charts - the 1m/5m is most useful when in action but the 30m,60m & 1d for context
So the platform I chose to use was x_trader and I use Velocity Futures. Prices vary based upon number of contracts traded and number of exchanges/feeds you want to trade but to do ES alone with velocity using their baked in x_trader then you are paying about $4.50 per RT per contract. This is of course negotiable. Costs drop significantly if you pay for x_trader yourself and number of contracts hike up but I would not suggest committing to this until it is financially worthwhile.
I have seen the IB have a comparable offer using their own proprietary trading platform so I would probably give that a whirl too as people rate them as a broker.
My personal opinion is that you will have an informational edge by trading an exchange traded product where you have visibility of the order book and order flow compared to the normal retail trading approach of using a chart alone. As markets generally reward you for having better information (providing you know how to filter it and trade it) then it should be relatively obvious why most institutional traders use x_trader and other similar platforms.
Good luck. Let us know how you get on and post some of your trades up here - all are welcome.
