The Jsa Moving Average was created by George R. Arrington, Ph .D. (Stocks & Commodities V. 11:10 (427-431)) and it is an extremely simple formula but has very many great uses. For one thing it acts as support and resistance levels and it also acts like a trailing stop. It gives a wide enough berth during extended up or down trends to let you ride the wave up or down and when it gets close to the price it means that it is a choppy market. Buy when the indicator line is green and sell when it turns red.
Let me know if you would like to see me publish other indicators or if you want something custom done!
Note: I'm republishing this because the original script couldn't be found in searches so this will fix that.
This is not a critic to your work it's just a comment. When one see the chart it gives the impression that if the close reach the last ploted level of the jsa indicator it will reverse, which is missleading, nothing wrong with the indicator but with the interpretation. The indicator only reverses if it reaches the 14 previous bar close, using the defauly length. I plot the src(14) for comparison.

@sal157011, I believe the reason why you are noticing that is because repainting is disabled by default and so the indicator doesn't use the latest bar in the calculation. I would turn it on and see if you notice anything different

@cheatcountry, I see the difference but the point is if you use jsa = (src + src(length)) / 2, as src is changing during the day so jsa changes, but if you use jsa= src(length) the jsa remains the same all day long.
when using jsa = (src + src(length)) / 2, src=jsa if src=src(length) but the target jsa is always changing.
when using jsa=src(length), src=jsa if src=src(length) but the target jsa never changes during the day.
As you see src=jsa if src=src(length) in both cases.
Of course if you use the data delayed by one day you resolve the repaint question but the jsa target value is not accurate.
Note: length should be between square brackets but I wrote () because this editor don't accept square brackets.
