Convert an indicator from prorealtime

i wish i would understand prorealtime's language to help you with the corresponding commands in MQL,

you might try to explain what you are trying to do and what the code does.

Hi gjol,

 I am trying to programm this code:

totalprice= (high[0]+low[0]+open[0]+close[0]) /4

a=20

tw= 20 

maximo1= highest[a](totalprice) // I calculate the maxmum value of 20 candels of the totalprice

minimo1=lowest[a](totalprice) // I calculate the minimum value of 20 candels of the totalprice

osc= (totalprice-minimo1)/(maximo1-minimo1)*100 //With this I create a new oscillator called osc

TMM = TriangularAverage[tw](osc) //Here I am calculating the triangular average with a period of tw=20 of the oscillator osc

WMM = WeightedAverage[tw](osc) //Here I am calculating the weithted average with a period of tw=20 of the oscillator osc

¿How can I make a triangular average of a series of number ? I can't find out any function of TriangularAverage or  WeightedAverage.

 I have only found out a function to calculate de moving average iMA, but I can only introduce: PRICE_CLOSE, PRICE_OPEN, PRICE_HIGH, , PRICE_LOW, PRICE_MEDIAN, PRICE_TYPICAL or PRICE_WEIGHTED. But a I need to introduce a series of numbers not a type of price (my oscillator osc).

 Thank you so much.

Best regards. 

calculation of TMA by the formula: TMA = (SMA1 + SMA2 + SMA3 + SMA4 + ... SMAn) / n.

where SMA is simple moving average
