Better Sine Wave Indicators can be used in Tradestation cold eld file, but if not can be in MT4 The code must be educated. The better sine wav is an improved version of the original John Ehler’s. The maker of the indicators which is in MT4 is the same the creator of Sinewave. As far as I know that all indicators are originally made for Ninja Trader or Tradestation but this one can be traded with MT4.
The original one which was introduced by John Ehlers was introduced for Rocket Science for Traders. His indicators were somewhat refined and it includes his code for measuring the dominant cycle. The code by Ehler’s were evolving over years.
The indicator follows the original TradeStation. There are bugs that were conserved, second bug in the median is added. Because of these it made the Ninja Trader were slower a bit. A lot of the traders do not recommend the older version.
