Hello Team,
I'm very interested in how the Parabolic Stop and Reverse indicator works. Does anyone have a simple algorithm they can share showing how to use it to do a simple buy when the trend is going up, and sell when it's going down? Hopefully in Python! :P
I found a few on the forums, but they were before the Indicator was added to core QC.
This is the Indicator as documented:
self.PSAR('BTCUSD')
var psar = PSAR(Symbol symbol, decimal afStart = 0.02, decimal afIncrement = 0.02, decimal afMax = 0.2, Resolution resolution = null, Func`2[Data.IBaseData,Data.Market.IBaseDataBar] selector = null) Thanks for the help!

Hi Drew, see the attached backtest for an algorithm using PSAR with charting system.

Thanks Jing Wu! This is great to see!

This would be a good simple algo to add to the examples.

Feel free to make a pull request Drew Baker! =) The open source drives the examples here in the website too.

Hi John Ener,
The PSAR indicator takes in a TradeBar object inside the Update method. To resolve the issue first, we need to create a TradeBar from the tuple and then do the Update. Refer to the following snippet:
