Indicator coding help, please

I've just started using MetaTrader4 and would appreciate help with coding the "Relative Slope" indicator (shown in Amibroker code below).

If possible could an mq4 version be posted, please?

K=EMA((H+L+C)/3,10);
S1=2*(K-REF(K,-1))/(K+REF(K,-1));
RS=100*EMA(S1,3);

[I then just need to plot the zero line and the RS value over it]

Notes...
1st line above:
K = 10 bar exponential MA of the expression (High+Low+Close)/3

2nd line:
REF(K,-1) is value of K for previous bar

Many thanks for any help.

Mike

Here you go.

care to elaborate how this indicator should be used?

Thank you Zen. Much appreciated.

The Relative Slope indicator can give good divergence signals with price; so you would use it just as you would any other oscillator for this. It is not the Holy Grail but I like using it.

Many thanks.
