Hello rdb,
Have been testing Your_Lucky_ EURGPD_v2 for two consecutive days on a demo account (3.000.- lev. 100) at FXDD, at the recommended period (21-5) adapted to CET on EURGBP (spread 5) and EURUSD as well as USDCHF. It gives good results, though small amounts.. 4-7 units, but consistently about 10 pips (100 units a night for me) which is good while sleeping.

I tried during daytime also, it gives some pips when the market is quiet. Interestingly enough, I had the Swiss Army knife operating on another chart of EURUSD and it entered a good trade on the (Your_Lucky_ EURGPD_v2) EURUSD chart !
I will continue testing various options and will report.
Am already pleased with the preliminary results, lets hope for the best !
Thanks and regards,
Jan
