Hi

I have a MC strategy, I need to transplant it to Algowizard an retest ,optimize.

So MC strategy code is :

inputs:Len1(14),Len2(80),sb(40);

variables:var1(0);

var1=(Average(close,Len1)-wAverage(close,Len2));

if Average(var1,sb) crosses over 0 then Buy  Next Bar at market;

if Average(var1,sb) crosses under 0 then Sell Short Next Bar at market;

Question:

1. I found that waverage function in MC is different from LWMA indicator in SQ

MC Waerage:

inputs:

PriceValue( numericseries ),

Len( numericsimple ) ;

variables:

var0( 0 ),

var1( 0 ) ;

var0 = 0 ;

for Value1 = 0 to Len – 1

begin

var0 = var0 + ( Len – Value1 ) * PriceValue[Value1] ;

end ;

var1 = ( Len + 1 ) * Len * .5 ;

WAverage = var0 / var1 ;

 

SQ LWMA indicator:

private void calculateLWMA(int CurrentBar, double newValue) {
int max = Math.min(Period, CurrentBar);
int multiplier = Period;
int divider = 0;
double sum = 0;

for(int a=0; a<max; a++){
divider += multiplier;
sum += buffer[a] * (multiplier–);
}

currentValue = sum / divider;
}

divider looks like Period*Period. So is differt from MC.  Whichi is better? Or no better, just be consistent between SQ and MC?

2. When I code average(var1,sb) crosses over 0 in Trading signals, How can I code? Because there are no “variable5” in

“ Compute from” option of average indicator.

So Is it possible to support to add custom variables  in price computed from option ? like period, shift option.

Of course i will try to add custom average function through programing in code editor first.

Thanks  very much

Hello,

yes, LWMA seems different from WMA since they supposed to be calculated differently

LWMA https://www.investopedia.com/terms/l/linearlyweightedmovingaverage.asp

WMA and others https://www.investopedia.com/ask/answers/071414/whats-difference-between-moving-average-and-weighted-moving-average.asp

You can simply check for two values cross but you always need to store 4 values. Meaning 2 values for Shift = 2 and 2 values for Shift = 1 so you have previous bar values and current bar values you can compare easily.

To check for the cross you simply setup these conditions:

if  Value1atShift2 < Value2atShift2 AND Value1atShift1 > Value2atShift1 – now you have a situation where Value1 crosses above Value2. This way you can setup any “Cross-over” situation …
