(2nd) Using trend.ex4 indicator to generate BUY/SELL signals

The EA uses two trend lines from this indicator the Trend1=140 periods (long) and Trend2=30 periods (short)

Simple logig. The long period Trend1 the refference, the base. All the signals is regarding what Trend2 makes different from Trend1

When Trend1 is bearish in RED is a "Selling season" and I have to identify each time the Trend2 Being different color (aqua) change back to the same color Trend1 (red), and then place a signal in the next bar inmediatelly it bar closes

Same with buying season, bullish, Trend1 is in AQUA color and I need to identify when trend2 being in a different color than Trend1 (red) and then change back to the same Trend1 color (aqua), the Signal and alert must be when the next bar/candle closes 

I would like to have the trends periods as a parameter, point with a circle in Trend2 when change to a different color from Trand1 and the signal as an arrow inmediately the next clandle (after being back the same color Trend1), closes

I need it works allways perfect at all,  I've tested "Trend.ex4" for some time, even I've cheked it in M1 for 24 hours with screenshots every 30 seconds and never repaint, so I'm pretty sure do not repaint at all, it is trustworthy. However I do not have the source code of this indicator (attached) needed to build this EA, now if the developer decide replicate this indicator in a way he needs, it is ok for me, just neeed the exactly same results...

I need the signals and alerts each time the logic complete, arrow signal must appear (BUY/SELL signal) And I need the source code as well.

Here I let the two examples in graphic
