counting variables

[tonynt]

Hello,

how can one count up the value of a variable, but only one time like

if(Rising(SMA(BarsArray[2],20))) varrising++;
if(Rising(SMA(BarsArray[3],20))) varrising++;

so that in total the value of the varrising would be 2 in this case (and not counting up with every new bar)

if(Falling(SMA(BarsArray[2],20))) varrising--;
if(Falling(SMA(BarsArray[3],20))) varrising--;

so that I would have varrising a value of 1 if one of both dataseries is falling.

OR/AND

another idea to resolve this is to give a fixed value like

if(Rising(SMA(BarsArray[2],20))) var2=1;
if(Rising(SMA(BarsArray[3],20))) var3=1;

but in this case I dont know how to add up with every bar like

valuevar = var2 + var3 + .....

Or could I do this aproach simply with int valuevar = var2 + var3 in onbarupdate?

So, because of being not a programmer I´m missing a brick with both ideas.


Thank you
Tony

Hello tonyt, and thank you for your question.

The most direct answer to your question that I may give, is that you will need to check on the current value of varrising . That is,

[FONT=Courier New]if(Rising(SMA(BarsArray[2],20)) && varrising == 0) varrising++;[/FONT]

In situations like this however, I find it is better to keep a data structure. That looks like

[FONT=Courier New]private class TrackRising
{
    public int riseCount = 0;
    public bool hasRisen()
    {
        return riseCount == 0;
    }
}

private TrackRising tracker = null;
protected override void OnBarUpdate()
{
    if (tracker == null)
    {
        tracker = new TrackRising();
    }
    [/FONT][FONT=Courier New]if(Rising(SMA(BarsArray[2],20))) tracker.riseCount++;[/FONT]
