@sktsec Oh, I just saw it now Thank you very much

@sktsec I can't find the block that can help me do this, could you point me to it ?

Which block should we use to determine the minimum/maximum of a moving average for a certain number of periods?
Thank you for your response, with an example of block construction if possible !

@l-andorrà Yes, of course, I'll explain how it works to get the expected result.

Example with a period of 10 (configurable).
The idea here is to apply a weighting coefficient to each encountered price as we go back in time. Then we'll manipulate this data to get our result.

In this example, we go back to progressively gather all the prices to multiply them by a weighting coefficient until we reach the closing price 10 periods ago.

Objective = we're trying to determine the price of the current period.

Step 1
Determine each weighted price to add them up at the end.

closing price of period-1 = 14973.54 * 1 = 14973.54
closing price of period-2 = 14934.54 * 2 = 29869.08
closing price of period-3 = 14919.04 * 3 = 44757.12
closing price of period-4 = 14919.03 * 4 = 59676.12
closing price of period-5 = 14933.02 * 5 = 74665.1
closing price of period-6 = 14935.03 * 6 = 89610.18
closing price of period-7 = 14958.52 * 7 = 104709.64
closing price of period-8 = 14,975.04 * 8 = 119800.32
closing price of period-9 = 14,974.52 * 9 = 134770.68
closing price of period-10 = 14,974.03 * 10 = 149740.3

Sum of weighted prices = 822572.08

Step 2
Add up all the weighting coefficients as follows:
(1+2+3+4+5+6+7+8+9+10) = 55

Step 3 = result = value of the price for the current period
822572.08 / 55 = 14955.85

That's it, so if you could help me model this with the blocks, that would be great.
Thank you !

Hi, i just need to know if an example exists to do it. Thank you for your answer.

I would like to draw a line using the charts and objects blocks to represent the following calculation on the screen:

  local i;
    local ii = Period;
    local LastPeriod;

    if period == source:size()-1 
    then
        LastPeriod = true;
    else
        LastPeriod = false;
    end

    while ii > 0 do

        if not(LastPeriod) 
        then
            ii = 0;
        else
            ii = ii-1; 
        end

        local Sum = 0;
        local SumW = (Period+2)*(Period+1)/2;

        for i=0,Period,1 do

            Sum = Sum + (Period-i+1) * source[period-i];

            if Redraw 
            then
                if i <= source:size()-1 - period and i > 0 
                then
                    Sum = Sum + (Period-i+1) * source[period+i];
                    SumW = SumW + (Period-i+1);
                end
            end 
        end

        Line[period] = Sum / SumW;

How can I do this ?
Can you help me?

Thank you !
