In addition to ranking by the N day return wouldn't it make more sense to look at either an N day E-ratio or MFE for a given period? Otherwise you might miss a pattern that ran up, then pulled back.

We can tag this a #FeatureRequest, sure. Can you point me to something that explains E-Ratio?

Ideally if you can show a chart of the e-ratio through time.

For example:
When running for a 5 day return you might see that the e-ratio peaks after 3 days and then turns down. You know your edge diminishes after 3 days and your exits should start to take you out of the position.

Depending on objective, the e-ratio's calculation may take a different form:

Okay, in WL6 the E-Ratio verses N-bars-held graph shown in http://www2.wealth-lab.com/WL5WIKI/PVERatio.ashx is available in the "Trade Graphs" Performance Visualizer. My question is where can I find the "Trade Graphs" Performance Visualizer in WL8? I do have the WL8 PowerPack Build 29 extension installed, but I don't see "Trade Graphs" anywhere. Maybe it isn't called "Trade Graphs" anymore.

On "casual inspection" of the E-Ratio calculation from http://www2.wealth-lab.com/WL5WIKI/PVERatio.ashx, it looks like the ATR term cancels out. Obviously, I must not be looking at that calculation right; I'll have to dig deeper.

Trade Graphs doesn’t exist in WL8 which is why you can’t find it.

@superticker, TG are not to appear in WL8. Over time we've integrated most of TG's features into WL8 one way or another so you can find their "influence" across many performance visualizers. However, some like the E-Ratio plot were discarded due to virtually no demand.

We already have the E-Ratio in the Extended Scorecard but I guess we'd need a separate #FeatureRequest for a better exposure i.e. through the Position Metrics visualizer.

We definitely need another metric than N day for PG and Candle evolvers. I often noticed that the good found patterns are not suitable for a strategy at all. So a few metrics to choose from is the perfect solution.

I noticed the E-Ratio in the Extended Scorecard, but that only delivers one E-Ratio value. I'm just wondering how to get an E-Ratio plot as shown on http://www2.wealth-lab.com/WL5WIKI/PVERatio.ashx ?

Is one suppose to go into Analysis Series and set E-Ratio as the Y-axes? Can Analysis Series do that now?

I appreciate the E-Ratio verses N-bars-held plot is a statement about the strategy's effectiveness and not about the viability of individual trading opportunities. But ...

I'm also wondering if it would be possible to compute a "running" E-Ratio value with an indicator that could be used to help make Buy and Sell trading decisions? For example, is the current E-Ratio history high enough to forecast a "low-risk" Buy opportunity or is E-Ratio history really meaningless in this context?

@superticker, this topic is not about plotting the E-Ratio in WL but just to clarify my point in Post #8, you cannot plot it now.
