Creating a new indicator..
Hello everyone, I wish you good work. The reason why I opened this topic; The 2 indicators I use are not available in Ninjatrader. I'm tired of paying other software programs to access these indicators, which I find very useful when investing.I have no coding knowledge. My 3 week attempts were unsuccessful..
I am attaching the codes of the indicators.

1 : Follow line indicator:
--((Explanation=The FollowLine indicator is a trend following indicator. The blue/red lines are activated when the price closes above the upper Bollinger band or below the lower one.
Once the trigger of the trend direction is made, the FollowLine will be placed at High or Low (depending of the trend).
An ATR filter can be selected to place the line at a more distance level than the normal mode settled at candles Highs/Lows.))--

When I tried to write these codes in ninjascript, I couldn't. Dear ninjatrader users can benefit if we create these indicators and add them to the ecosystem. In this way, we make successful investments with the power of ninjatrader without paying for other software.
