Portfolio of robots (part 2): Pearson correlations of price data for different time periods

I want to build a portfolio of robots (Expert Advisors) for trading various intraday strategies on Forex and Binary Option platforms. This is the sub-project #2 of a bigger project (see my other posts).

Strategy #B:

• The EA should calculate Pearson correlation of price data for different time periods (e.g., days, hours, minutes, seconds) for three scenarios:
• Two symbols
• Set of multiple symbols (up to 10)
• Symbol and a template for a price pattern, stored in an external file
• The EA should allow to perform different operations (e.g., averaging) of correlation values for different timeframes and multiple symbols. For example, it should be able to average correlations between EURUSD and GBPUSD for the last 30 hours.
• Buy and Sell signals are generated when results of the operations exceed a particular threshold
• The EA should support three types of position openings:

§  Using standard StopLoss and TakeProfit values

§  Using Trailing Stop

§  Using a binary option framework with a predefined time expiration

• Parameters for statistical properties, periods, symbols, thresholds and position details should be read from an external file.

Additional requirements:

• The EA should be able to read external data for testing (ASCII file).
• I am looking for someone who will explain me in details each line of code. I have some experience with scripting and writing strategies in EFS ESignal language. I want to learn MQL, so that I can modify and maintain the EA myself eventually.
• Also, successful experience with developing profitable strategies for real-money (not demo) accounts is highly desirable.
