Plot Relative slope

[Manish Chugani]

Hello,

There is this Relative Slope by Dimitris Tsokakis and am trying to plot it in MT4 but with no luck. Am only able to get the first buffer to plot and not the rest.

Please kindly guide. Thanks !

K=EMA((H+L+C)/3,10);

S1=2*(K-REF(K,-1))/(K+REF(K,-1));

RS=100*EMA(S1,3);

Plot(RS,"RS",colorGrey40,styleLine|styleOwnScale,0,0,0,0,2);

The above four lines of code is all there is for Amibroker Afl. But when the same comes to MQL, it seems so complex.
