did someone have tried such idea of generating strategies?
- E.g i use data from 2018-2019 let them generate
- than we use from the collection before and change data from 2018-2020
- so than we will have simulated 1 year forward testing of each startegie and can sort them out and can see the robustness
What do you think?
Lots of people do this as a way to eliminate forward testing. From my personal testing this will only get you part of the way there.
For e.g. create some strategies using the default data from JFD. Trade those strategies on a JFD demo account (same data as they were generated on) for 1 month and then re-import them back into EA Studio and change the data horizon to match the demo account dates. You will find that the results will not match, and in some cases and be quite different between what EA Studio thinks would have happened and what actually happened. This is due to many things, the data feed itself, execution issues, using indicators that use weighted metrics or volume etc.
I find the only reliable result is to actually trade the strategies on the account they are going to be used on. Anything other than that is best guess.
You can improve the best guess though by using WFA, OOS etc.
