Here is a little strategy from me. Profitable over a full 200,000 bars in a small time unit. Unfortunately, the yield is not huge. But the interesting thing is that you can trade well with just a single filter for such a long time. Also works with a Bollinger entry and EMA60 as a filter.
Maybe someone has an idea how to get more yield out.
Unfortunately, I have not yet found any other currency pair that works consistently well in a similar manner.
Ideas and improvements are very welcome.
