Expert advisor based on cointegration and autocorrelation needed

Hello,

I need an ea based on excel file. It does pairs trading based on cointegration and autocorrelation.

-let's say it's a H1 charts

-in column A goes close price minus open price of audusd

-in column B the same of eurusd

-next, it has to calculate slope. the same formula as it is in excel

-it has to lookback at least 5 candlesticks to calculate slope

-same goes for calculating intercept

-from slope and intercept cointegration is calculated

-from cointegration, x is calculated

-next, autocorrelation is calculated using same formula as in excel

-finally, after all this is calculated buy and sell can happen

-to sell audusd and buy eurusd at the same time, x of the previous hour must be greater than 0, and autocorrelation of the previous hour must be less than 0

-reverse is for buy audusd and sell eurusd

Thanks.
