GRAB TIndicator from Pinescript to Prorealtime

  Dear All,

  I just found this indicator on Tradingview code (Pinescript) that I found interesting:

  https://www.tradingview.com/script/1HAKnNRc-Grab-Trading-System/

  I would be interested in evaluating the outcome of this indicator on Prorealtime.

  I attached the following files:

  1. file with the screenshot from Tradingview in which I applied this indicator to US500 Future (1 hour timeframe)
  2. file with the Pinescript script

  I would be interested in the indicator behind the trading system rather than the trading system itself.

  Thanks to anyone would like to take the chance of having a look to this request

  Best regards

  Lorenzo

  Hi @lorebruno

  Here is the indicator of the Grab system…

  I have set the “color fills” in the graph, the fills are not exactly the same, but this is the best I think is currently possible.

  Thanks a lot for your reply JS!

  What do you mean with ““color fills” in the graph, the fills are not exactly the same”? You refer only to the colour or also to the indicator value?

  Hi Lorenzo,

  The color filling between the different support and resistance lines can be processed in your code but you can also set it in the graph itself. I did the latter…

  The indicator values correspond to the original code, but the (color) fill between the different lines may differ slightly…

  Regards Jaap

  Thanks for the prompt reply!

  If it is only about the colour it doesn’t matter, the important thing is the the “numeric value” output is the same!

  You can use COLORBETWEEN to add color fill between 2 values.
