Calculate the angle of a trendline

[blooey]

Hi all,

I'm new to the forum but have found a few great indicators that have helped me tremendously...like the SSL Hybrid and super trend. Thanks to all who have translated these to thinkscript.

My question: is there an accurate way to calculate the actual angle of 2 points in thinkscript? I'm aware of how to calculate the slope mathematically, but on a chart, X can vary based on how large the candlesticks are displayed and there doesn't seem to be a way to get the current size of a chart's candle X size. It would be nice to know the angle of a moving average/trend line to gauge how strong the trend is.

Anyone know how to do this in thinkscript?

@blooey The term you are looking for is "slope" in your searches... There are several indicators in these forums that address "slope"... However, there is one caveat to slope... It will vary based on zoom levels... The slope will change as zoom is increased/decreased, which is why there are so few implementations... Slope is relative rather than finite...

That being said, the TOS Trendline drawing tool can display the angle of the line when you hover over the line once drawn... But, again, that angle will change based on zoom...

For this reason, "trend" means more than "slope" or "angle"... Focus on what really counts and doesn't change due to zoom or timeframe...

Since the x-values are evenly spaced (generally time based data) - your "run" between any any two adjacent candles will be 1.
The "rise" or difference between the candles in value. Such as (close - close[1]) that is the close compared to the prior close.

Slope is rise/run or (close - close[1]) / 1 And this equals (close - close[1]).

Similarly valid slopes could be:
(open - open[3]) / 3 --- The slope of the open compared to 3 periods prior.
(MovingAvg - MovingAvg[10]) / 10 --- The slope of a defined moving average compared to its value 10 periods ago.
