Correlation-based 4-pair basket grid system

I've an interesting thought here based on Dreamliner's Hedge and Correlation System. If somebody can develop a grid ea which generates grid of simultaneous buy-sell and sell-buy orders of highly correlated pair trades with a set take profit target. Normally a grid system works very well in ranging or weak market and by selecting a highly correlated pair we'll be simulating the conditions of ranging/weak market conditions which can have possibility of very good results. Pairs selection will be the key to success in this approach, we need to have a market neutral basket. I'm not a programmer but I'm sure somebody will come forward to code this and take the discussion forward. Look forward to hearing from you guys what you think about it.

For this strategy we'll need one indicator which tells us the difference of price difference between two correlated pair of pairs. Suppose we are going to trade A/J, U/J, N/J AND E/J. We want to make a grid of buy and sell orders of the spread between [{PriceAJ-PriceUJ}-{PriceNJ-PriceEJ}]. So we'll need an indicator which shows us the above spread on the chart for selecting the best ranging or slow moving basket to trade. I've and indicator which shows the price spread between two pairs which I'm attaching here for reference.

Got it
