Are you searching for an Auto Trendlines indicator for TradeStation that automatically draws horizontal trendlines? You fund it!
Our indicator draws two horizontal trendlines, one support (Red Line) and one resistance (Green Line).
With default sets, the indicator calculates the highest high and the lowest low of the last 20 bars and draws two in the previous 100 candles.
If you want to calculate the highest and lowest of a more significant period, you only need to change the BackHigh_Calc and BackLow_Calc inputs.
If you would like to draw longer trendlines, you have to change BackHigh_Draw and BackLow_Draw inputs.
