Code snippet for calculating slope

This is an example of one form that I picked up from a strategy posted by wh. This example is for the 20 simple moving average. You can substitute any series based value for SMA(20) whether it be a standard NT indicator or a custom indicator. The TickSize will modify the scale for the instrument of the chart.

sma20slope = (int)(radToDegrees*(Math.Atan((SMA(20)[0]-(SMA(20)[1]+SMA(20)[2])/2)/1.5/TickSize)));

include the following in the variables section:
privatedouble radToDegrees = 180/Math.PI;
privateint sma20slope = 0;

I have just started using it so I can't comment on how well it works, but you could use a series for the slope result instead of an integer and plot it in a panel for testing. Please report back on your findings.

at first - thanks for the snippet

this is the common formula with two enhancements.
- the usage of two older Values (like a "mini" Moving Average) results in a more stable Slope-Calculation
- consider the Ticksize try to standardize price-skales with different amount.

The Snippet DID NOT WORK on Indikators, which oszillate between positiv and negativ Values.

--> you can use the common Slope() Command.

Degree = Slope(SMA(14), 1, 0) / Ticksize;

The Ticksize Standardization is imprecise, because it gives us no adjustment if you switch between a 1Minute and 10 Minute Timeframe, and it also did not differenciate between price-data and indicator-data (i.e. from -1 to +1).

This formula is from Woodies CCIClub. Ken Wood (Woodie) uses a calculation of 1.5 bars back . Hence the

Code

(SMA(20)[1]+SMA(20)[2])/2)/1.5

Slope is calculated on Rise/Run (From where we are how many bars back).

You can add a variable for Barsback.

emaslope = (int)(radToDegrees*(Math.Atan((EMA(Period)[0]-EMA(Period)[BarsBack])/BarsBack/TickSize)));
