Hi,

I am new in metatrader 4, I come from prorealtime, but I think that metatrader 4 is better than prorealtime and I would like to learn to program in Metatrader4. 

The problem is there are a lot of funcitons of prorealtme that don't exist in metatrader and I think that I have to program them.

 This is the indicator that I would like to convert to metatrder4:

Rem Zapatero Oscillator v1.1
Rem v1.1
Rem 2014-04-28

// a input parameter
// tw input parameter
maximo1= highest[a](totalprice)
minimo1=lowest[a](totalprice)
osc1= (totalprice-minimo1)/(maximo1-minimo1)*100

TMM = TriangularAverage[tw](osc1) //RED
WMM = WeightedAverage[tw](osc1) //BLUE

RETURN osc1 COLOURED(0, 0, 0) as "osc1", TMM COLOURED(255,0,0) as "TMM", WMM COLOURED(0,0,255) as "WMM"

And I've got another quiestion. How can I visualize a period of time of 2 hours. I only can M1, M5, M15, M30, H1, H4, D1, W1 and MN?

Thank you very much.

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.

in the meantime... Alphabetic Index of MQL4 Functions (600+)

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.

But nothing. If you want something else, you have to code it.
You state you know how to calculate a SMA(n), the TMA= (SMA1 + SMA2 + SMA3 + SMA4 + ... SMAn) / n so code it.
learn to code it, or pay someone. We're not going to code it FOR you. We are willing to HELP you when you post your attempt (using SRC) and the nature of your problem.

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

where SMA is simple moving average
