The system you posted uses gaps. As forex is a 24 hour market, there are only a few gaps, most happen when the market opens on Sunday. However, someone can decide that a forex day is only between the open of Europe to close of US trading. In that case, there will be more gaps and the strategy can be formulated. However, it is beyond my capability to create a day between two given hours, so I can't do it. Rest of the rules are simple enough for me.

Hope someone takes up the challenge.
