# Bear count in the last 27 minutes

26

Hello boys,

Can someone help me with a script for the next issue:

I want to know how many red candles there are in the last 27 minutes.

In the example below you can see that there are 9 red candles out of a total of 27.

Let's assume that the next candle ends in red.

That means we have 10 red candles in the last 27 minutes.

And simply to appear on my screen: "There are 9 reds, 18 green candles."

If no one can help me with this script, can you at least tell me how difficult it can be to create one?

AIS RED CANDLES COUNTER INDICATOR

21914

Bosinceanu Claudiu Catalin:

Can someone help me with a script for the next issue:

I want to know how many red candles there are in the last 27 minutes.

In the example below you can see that there are 9 red candles out of a total of 27.

That means we have 10 red candles in the last 27 minutes.

And simply to appear on my screen: "There are 9 reds, 18 green candles."

Not compiled, not tested; just typed.
```input int lookBack = 27;
int start(){
int nUp=0, nDn=0;
for(int iBar=lookBack; iBar>0; --iBar){
if(Close[iBar] > Open[iBar]) ++nUp;
else                         ++nDn;
}
Comment( StringFormat("There are %d reds, %d green candles", nUp, nDn) );
}```
Not compiled, not tested; just typed.

Thank you very much
If I use the script on a range of 20 candles, it updates each candle
If I use the script on a range of 100 candles, it updates irregularly, once every 2-3 candles
Where the problem is?

Sometimes after the arrival of a new candle, the number of red and green candles remains unchanged
That is, the new candle has the same color as the candle that was last and left

And just in case, I added an indication of the time until the end of the candle
