Long-Short Ratio

[Rodondo]

Hello,

I'm looking for the possibility to count the numbers of the last 30 Candlesticks, how much is it rising, falling or unchanged? The result (15 rising - 10 falling - 5 unchanged) should be indicated to realtime in the 5 minutes Chart?

Thank you for your assistance in advance.

You will need an efs to do that. In the script first declare three local variables (ie inside of function main) which you will use as the counters

var CntrUP = 0;
var CntrDN = 0;
var CntrUNCH = 0; 

After that you run a for loop that looks back the desired number of bars (in this case 30 as per your example), verifies each condition and increments the appropriate counter if the condition returns true

if(getBarState()==BARSTATE_NEWBAR){
    for(var i=1; i<=30; i++){
        if(close(-i)>close(-(i+1))) CntrUP++;
        if(close(-i)<close(-(i+1))) CntrDN++;
        if(close(-i)==close(-(i+1))) CntrUNCH++;
    }
} 

You can then use the variables CntrUP, CntrDN and CntrUNCH in the return statement or to write the totals to the chart.

Hello Alex,
thanks a lot for your very quickly answer.
Do I need for the efs the GET Studies? If yes I don't have it.

Kind regards

You do not need the AdvancedGET Studies to run an EFS unless this is using specific AdvancedGET functions or studies.
