ASCTrend Matrix – From MT4 to Pine Code

• 02/11/2021 at 4:16 AM #161006
  frejosan

  Hello,

  I’m looking for the conversion of the ASCTrend Matrix from MT4 to be used in Tradingview.

  The ASCTrend Matrix has MTF capabilities, and is one of the indicators used with the Genesis Trading System in MT4.

  Thank you very much.

  John O.

  Here is the indicator code for MT4

  /*————————————————————————————
  Name: ASCTrend-Matrix.mq4

  Description: Two timeframe ASCTrend Matrix 4TF:
  Consists of the following indicators:

  Note:
  Requires that the following indicators are installed and working:
  ASCTrend1i.mq4,

  Change log:
  2013-05-03. Xaphod, v1.01
  – Fixed updating of bars on all timeframes as new data is being downloaded.
  – Draw blank dot if there is not data for the bar.
  2013-04-??. Xaphod, v1.00
  – Derived from ‘ASCTrend1-Matrix 4TF’
