This is the indicator that I use on my chart. It is the only indicator I use on a price chart. As far as price is concerned, all I care about is Support and Resistance. I use this indicator on a one minute chart of the ES E-mini SP 500. It plots a Resistance line as soon as a Peak signal fires. When the second Peak signal fires, it plots a new Resistance line, and extends the old Resistance line in a different style. The same happens for Support lines.

This indicator in in Easy Language code, programed in TradeStation. It is shown below, plus attached as an ELD file.

Here is an updated version. This version will show the price bubble on the price axis. I added a couple of plot statements, and made the plots a point style. That way there is no connecting line between the different levels. If you make the two plots a point style, and keep the line weight at the lowest setting, then the plot will never show. Why don't I want the plot to show? Because I don't need the plot, the trendlines are what I want to see. Then why put a plot on the chart that you don't want to see, and you won't see? So that the price bubbles show on the price axis. That way I know what the price is of the support and resistance lines.

 

So I figured out a "work around" for getting a price bubble to show on the price axis. The trendlines will not show update data, only plots show the values.

 

I got rid of some variables that were not being used, and cleaned up the code a little. I had programed this in another language, and had to rework it, and didn't need some of the old variables.

Hi Tradewinds,

 

Thank you, Thank you and Thank you for the support and resistance script. I had been looking this for a while.

 

Can u please let me know how many bars it takes to plot the support or resistance. for ex, if we are plotting parabolic sars, the green dot or red dots are plotted after the three bars have moved ahead. its more like lagging 3 bars.

 

Once again, your script help is greatly appreciated...
