zalis Hi Conny, there are a few approaches to this, both have been mentioned by Paul in his videos and i am in the process of backtesting/forward testing both.
- Do a monthly rolling 12 months optimization,. i am no sure if you have all the Neptune bots but doing 10 over one week end would be difficult so maybe spread them out
- Do a weekly rolling 3 month optimization,..
Personally, i'm steering for the 2nd option as it optimizes the robot for more recent price action. I think the 12 month option is still valid however be aware that the markets were still a little all over the place due to COVID so i am assuming if this is included in the modelling it could skew the final settings,... of course anything further back than 12 months and includes early/mid 2020 is junk in my humble opinion.
I would suggest that before any optimization on a particular currency pair, take a look at the relevant time frame price chart and see if you have a nice balance of bullish/bearish trending price action as well as consolidating price action, this way, i think you will get a nice balanced set of settings.. if you are more advanced, then also check the ATR at the beginning of the date range and the end and make sure they are not wildly apart.
