MQL4 indicator modification

Hello, I need to modify "Volty Channel Stop on jurik-for [login to view URL]" and same code in it's EA "Volty on jurik Trailing Stop [login to view URL]". I want to use "10.2 TMA slope v.1.4B [login to view URL]" to automatically adjust the "extern double Kv = 2;" according to the current TMA slope. To Add these lines: Use TMA Slope: True/False TMA Slope 0.8=3 // If TMA Slope is above +/- 0.8 set Kv=3 TMA Slope 0.4=2 // If TMA Slope is between +/- 0.4 and +/- 0.79 set Kv=2 TMA Slope 0=1 // If TMA Slope is below +/- 0.39 set Kv=1 That is it. Thank you
