...Based on the results above, I recommend using both SL to BE and Trailing Stops with the EA.
The recommended settings for the parameters are:
ProfitTargetPips=80 StopLossPips=40 BreakEvenAtPipsProfit=24 TrailingStopPips=40
This setting came as the best and most stable year by year according to my backtests (1, 2, 4 years back).
