I'm trying to create a condition in RealCode with a 50 day moving average moving up quickly.
I have tried this - but it's not working too well - some of the stocks that pass actually have a flat 50 DMA.
If price.avg(50, 0) > price.avg(50,1) then
Pass
End If
Thanks in advance for your help.

If you want to use the "Moving Up: Quickly" that can be created by right-clicking on the Moving Average and selecting Create Condition | Moving Up and adjusting the Rangefinder to Quickly, then you should probably do just that as the algorithm used to define Quickly is not public.
Otherwise, you will have to define quickly. I'm actually relatively confident that 50-Period Simple Moving Average is in fact always moving up when your RealCode Condition returns True as it exactly matches the results of the following Condition in all of my tests.
If Price.Last > Price.Last(50) Then Pass
And does not return True when the following Condition returns True:
If Price.Last = Price.Last(50) Then Pass

Hi Bruce - thanks for the reply.
I'm not having much luck with right-clicking on the Moving Average and selecting Create Condition | Moving Up and adjusting the Rangefinder to Quickly. The scan produces a quite a few of stocks where the moving average is not moving up quickly. Some are actually moving down. For example, right now if you created one of these conditions and ran it against the Nasdaq 100 Component Stocks, you would see that AKAM's 50 day moving average is actually sloping down a little since the beginning of January. Some are slightly sloping up and others are moving up quickly.
I tried dragging the 50 DMA into the code window to program against that and it created a variable called MA, but there is no intellesense when I type MA. (dot) - so I'm not sure if we can program against it to find an upsloping MA.
I tried Price.Last > Price.Last(50) and there are plenty of hits, but quite a few are higher than Price.Last(50) but they have retraced so much that the MA looks like an upside down horseshoe (exagerating a little here) and they don't really reflect an upsloping 50 DMA. If you have any other thoughts, I'd love to hear them.

What Move Period are you using when creating a Moving Up Quickly Condition? It defaults to one and my initial response was based upon this and your original RealCode which also only compared the current Bar to the previous Bar.
How do you want to unambiguously and objectively define "upsloping" and over what Period? Is it just a positive Linear Regression Slope over the Period? A positive Net Change over the Period? Some combination of the above? Something else entirely?

I'm using the default of 1 Move Period.
How I'm trying to define "upsloping"
The best way to answer that is to explain what I'm trying to accomplish.
I'm trying to find stocks that have been in an uptrend and have recently pulled back. My logic was this; If the stock has been in a strong uptrend over the last 50 days, then I consider it to be trending higher, so if it pulls back and has a correction, then the pullback "may" be temporary and the stock could continue higher again (in the direction of the trend). Creating the 50 dma was my initial thought for defining the uptrend. However, you mentioned a couple of other things... positive Net Change, positive Linear Regression. Maybe that's the way I should go?

I just tried something that seems like it should work and it doesn't. Either I'm doing something wrong, or I have a problem with my Stockfinder.
Could you please try this to see if it works on your machine?
1. Create a new "default" layout.
2. Add a Linear Regression Trendline to price and accept the 30 day default.
3. Right click and choose "Create Condition"
4. Select "Moving Up" from the drop down list.
5. Leave all properties at their default settings and click OK.
The new condition is added to the chart.
Now right click on the newly added condition and choose "Scan"
On my machine none of the symbols light up (no hits) but right now on my machine DIS is the first stock listed and the LinReg Trendline is clearly in a strong uptrend. MS is another that's in a strong uptrend.
Shouldn't this have lit up? Am I doing something wrong?

The Linear Regression Trendline only has two points. The starting point and the ending point. It also only Plots for the most recent data and does not have any historical values.
You will normally want to use either a Linear Regression Indicator or a Linear Regression Slope Indicator when making Linear Regression based Conditions.
