Dear All Expert Members of this Group! I have metastock pro 7.0 version. I need to know the system tester & expert system tester formulaes for the MACD DIVERGENCE BUY VOLATILITY for following type of exploration. In the exploration i have following exploration formulae for MACD DIVERGENCE buy volatility: Col A: md := MACD(); mdhist := md - Mov(md,9,E); Correl(((Sum(Cum(1)*( mdhist ),100))-(Sum(Cum(1),100)* Sum(( mdhist ),100)/100))/((Sum(Power(Cum(1),2),100))- (Power(Sum(Cum(1),100),2)/100)),((Sum(Cum(1)*C,100))-(Sum(Cum(1),100)* Sum(C,100)/100))/((Sum(Power(Cum(1),2),100))-(Power(Sum(Cum(1),100),2)/100) ),12,0) Col B: H > Ref(C,-1) + 1.8 * Ref( ATR(10),-1) Col C: V > 1.1 * Ref( Mov(V,10,E),-1) Filter: colA AND colB AND colC AND colA <-0.80 So Dear technical expert members you are kindly requested to help me in my above mentioned query as soon as possible. I will really apprecieate that! Thanks! With Best Regards! Paras Sharma.
