There's a well-known manual forex strategy available which I have purchased. I will not disclose the name of the strategy.
While the material is copyrighted, the idea behind it and the math are not.

Here are the basic rules; if someone knows of an existing EA that operates similarly or can code one up that would be neat; it would be nice to backtest the strategy.

1) Obtain weekly high, low, close. Exclude Sunday.
2) Subtract the low from the high, divide by three.
3) Add the figure obtained in step 2 to the close
4) Subtract the figure obtained in step 2 from the close
5) On Monday set two stop orders, one for a buy generated in step 3, one for a sell generated in step 4.
6) Cancel pending order once other is filled.
7) PT= 50-75 pips, SL about 75% of PT.
8) Breakeven stop after X-pips.

That's it.

Any help appreciated.
