I am glad to hear from you. It seems that the Forum blocks the posts that have more than 1 image. Of course, we will solve it, but in the meantime, if you want to share screenshots just go for one per post.
Yep, quite normal that you get fewer strategies if the costs are bigger. So focus on the data you can get.
I would suggest you do the following:
Download the data from the Forex Historical data app, and insert the symbol settings for the broker you are about to use.
The data in the app is complete without missing bars.
Also, you can increase or decrease the number of trades that the strategies will open according to the number of bars that you use.
For example, if you use on H1 50 000 bars and you run another generator with 25 000 bars, but in both, you request min 300 counts of trades, It is obvious that the second generator will give you strategies that are 2 times more active.
