Custom Indicator Request PSAR

Hello Tiki and All - I'm hoping someone can convert the Parabolic SAR code I use on TOS so that I can use it here on Tradovate. It's a custom indicator request because there are modifications to the existing Tradovate PSAR indicator that I find really helpful. Thank you and here's the code I'd like to have converted to Tradovate

Heya Bob, I went ahead and installed that indicator in TOS to get an idea of what it does, but the plot is not showing up. How do you have this configured and what symbol / chart combo do you use?

Hi Dave - Thanks much and here's a screen shot of how I use PSAR in TOS. I should note this install in TOS is as a strategy not a study. That's perhaps why it didn't show for you and here's a link for help with Strategy installations http://www.smalldoginvestor.com/2011/06/how-to-get-one-of-my-studies.html

Thanks again, Bob

Thanks Bob, Tradovate comes with the Parabolic SAR indicator built in. Check it out, it should be in your menu. If you're looking for an automated strategy like TOS, that capability doesn't exist yet.

Thanks Dave - Although the TOS PSAR graphic example I provided loads as a strategy in TOS rather than a Study, I have always used it manually, never automated. I like the arrows signalling Buy and Sell triggers provided by the code I shared. Many thanks, Bob

Got it! So Tradovate doesn't have those arrows, so struggling with how to help ya out here, best we could do is see if this is something they could add to their platform, as I agree it could be handy for pointing out buy/sell signals.

Thanks much Dave. I also find the use of arrows for EMA crosses above or below (example: the 3 EMA crossed above the 8 EMA) is very helpful. I appreciate your comments and continued efforts to assist fellow traders. /Bob
