Indicator conversion from MQL4 to MQL5 and EA build on it (in MQL5)

The job is very simple. An indicator that has less than 90 lines I want to be converted from MQL4 to MQL5. Than in MQL5 build an EA that will open BUY when the 2 arrows of the indicator are both BLUE  at the same time and close it when the 2 arrows are different. In the same way open an SELL order when the 2 arrows  are both RED at the same time and close it when the 2 arrows are different. You can use the MQL4 code (that is functionally) to better understand what I mean.

#property indicator_separate_window
#property indicator_minimum 1.0
#property indicator_maximum 3.0
#property indicator_buffers 6
#property indicator_color1 Blue
#property indicator_color2 Red
#property indicator_color3 Yellow
#property indicator_color4 Blue
#property indicator_color5 Red
#property indicator_color6 Yellow
