Hello,
Your formula is NOT RSI. Or.. not RSI in CLASSIC sense.
RSI used by AMiBRoker is CLASSIC one based on single CLOSE price.
Your formula is based on OPEN and close price.
http://www.stockcharts.com/education/IndicatorAnalysis/indic_RSI.html
For classic formulation you would need to use difference in CLOSE prices (today-yesterday)
instead, see the formula below.
period = 14;
rsi_r = Close - Ref( Close, -1 ); // DIFFERENCE in close price
rsi_rs = Wilders(IIf(rsi_r>0,rsi_r,0),period) / Wilders(IIf
(rsi_r<0,abs(rsi_r),0),period);
Graph0 = 100-(100/(1+rsi_rs));
Graph1=RSI(period);
www.google.com is good place to look at for indicator definitions.
Best regards,
Tomasz Janeczko
