I think you are not doing anything wrong! What I see is too high number of ambig. bars and that needs to be addressed. The curve might suggest an indicator fault, but lets keep this to one step at a time.

Please upload your strategy.

Richie, I'm talking about backtest quality. I repeat - BACKTEST. Read a bit here about ambig. bars and what it means: https://forexsb.com/wiki/fsb/manual/ambiguous_bars

All in all, the ALF indicator in its current setting (in your strategy) is not showing meaningful values. I traced it back to the original version, so not a reliable indicator to say the least. There is one issue I can't explain and I will discuss it with the developer. But what I can say is the strategy is showing over-optimistic results, partly because of the indicator and the other part I will clarify with the developer when he gets back. Drop the strat.

Do you have FSB complaining about bad data? There are error messages if there are gaps and missing days.

What you have to do is to make sure you have lower timeframe data, which covers the underlying timeframe. In your case you have to have sufficient number of bars below H1 TF. Then intrabar scanning can make a difference in reducing ambig. bars. It is a case of uncertainty, not data quality.

Over-optimization is not the issue here. ALF is not working correctly when median value is higher than the lookback period, the value ends up in stratosphere, it is not relevant to price data. I'll have a thinking session about this and I'll try to fix this issue.

Footon, great job with the indicator.

Thank you for your efforts!

As far as I see, only the creation date is visible. If you download them, then you can compare the difference in creation and modification dates but it's not quite practical.

Are you really sure there were more indicators? Currently there are 105 indis, 81 with mqh version for export. Maybe you're mixing up those numbers? And again as far as I know every author can maintain their own indis and essentially it is their right to upload or remove them, maybe some people removed theirs.

I think user Yavor had a hand at developing the repo. https://forexsb.com/forum/topic/2575/hey-there/
Maybe he can take suggestions for improvement, but on the other hand I told him that for instance I can't open indicator code in full in the repo, he was only amazed by that. Oh, and then there was the notorious forum software update, which prevented file upload - it lasted for months. And the post-like function. I had the nerve to down vote him once and he came after me for that I think you got the idea, sorry for ranting, but some things are hard to forget
