Rosaline is an EA that operates with a refinement of a simple strategy based on RSI + bollinger bands + ATR mainly on Gold, EU and OJ.
The EA is designed with manually settable 'equity protect' that goes to protect capital from drawdowns.
What does this mean?
If you are thinking of using it to pass a challenge you can do so because thanks to this 'feature' you are covered by the classic daily DD rule.
Example: on a 100k account you can set a hedge at -4%. If EA reaches that floating loss it shuts everything down and restarts the next day.
You can only trade with RSI or BB or both for double confirmation
What about the stop loss?
It can be fixed or open with multiple fixed or martingale positions (de gustibus)
And the take profit?
Again, it can be fixed for more swing activity on medium/high timeframes or wide and with tight lockprofit and trail stops for scalping
How best to use it?
It is not a 'copy and paste' EA. After downloading it you have to perform a "slow" optimisation of the last quarter on the instrument you want to use "XAU, EU or GU". Back and forward test to find the best settings. You can backtest every parameter. The ideal is to test everything from pip steps to RSI. 3 months backtest with 1/3 forward.
You can stick to a single instrument such as gold or spread it over 3 or 4 instruments splitting the max risk of the equity protect
