hi.. yup i use the default.
somehow, what catch my attention is to play with the trail start #, & trail %
The trail %, if you longed for higher locking profit then put e.g. (From 50%) 66% for instance, it should lock when pips goes -ve direction. Alway a but, then also potentially missing chance to wait for spike profits if the instrument fluctuation is high.
The latest TRAILING EA has come with default 80% of trail_percent (correct me if am wrong).
seriously, i am still blur on how the decay works blehhhhhhh
The reason behind the decay is that it makes this trail highly customisable.......
With a normal trail, if you were trailing at 50%, you would lose half the pips that were locked in at any one time, so lets say, the profit runs to 200 pips, you will eventually only bank 100 pips on the retrace. My thinking is that it would be nice to lock in more of those 200 pips.
The trail allows you to provide a wide trail eg 80% and then wind the trail in over time. In fact, you could use this as nothing more than a move to break even if you prefer. ie trail @ 100% after say 30 pips with use decay false.
The exact settings will be a function of the strategy that you use to enter. If you are using a breakout strategy on the GBPUSD as an example, my studies tell me that the average breakout lasts 50 minutes before a significant retracement occurs. You would then have a wide trail....maybe 100% from 10 pips and then at 45 minutes I would use the exponential decay to rapidly move the trail to 10% and then leave it there.
These settings will be different if you are using a trend following strategy......
I don't trade FGB, so I cannot tell you the best settings for FGB. Run some tests on demo and compare is the best way to find out the optimum settings. I am working on developing an adaptive technology where the EA will record its trades and analyse various outcomes with different settings to determine the optimum settings......sort of like self-optimisation.
