# Explore Stocks that respect desired EMA

I want to list stocks that respect a specific EMA. For example, I want to list those stocks in my watchlist which respect their 20 days EMA.
To do this, I was thinking to consider the percentage of the daily bars that close above required EMA. For example, I assume a stock respects its 20 days EMA if 70% of its daily price is close above 20 days moving average.

I wrote the following code. However, although it counts and calculates the percentage correctly (as I debugged), it does not provide the result I am looking for.

For example, I know that Blink recently respects its 20 days EMA but does not appear in the results.
Besides, I want the list of the stocks, not the list of stocks at a different date that price was above EMA.

Appreciate if someone can advise me.
Thanks

``````Percenage = 70; // the percentage of price bars close above desired EMA

desiredEMA = 20;

count = 0; //Number of days that price Close above desired EMA

m = EMA(Close,desiredEMA);

for (i = 1; i < BarCount; i++)
{
if (close[i] > m[i]) count++;
}

Filter = (count/BarCount)*100 > Percenage;

Here is a result I'm getting from the above code. But the ideal output for me would be just a list containing AAPL and FB. For posting questions on the forum, you are required to get "Verified".

Thanks for your note. I did it.

@Sepideh, Glad to see you got verified.

As to your issue, it depends on what you are really looking for. You will probably have to refine your expectation and your code...

Also, your method of determining the % (a loop), is not recommended in AB/AFL.
A more AB/AFL method is using the arrays.

``````// Stocks Respecting EMA
// From forum
// Code by Snoopy.pa30

pDesiredPercentage = Param("Desired Percentage", 70, 1, 100, 1, 0);
pDesiredEMA = Param("Desired EMA", 20, 3, 99, 1, 0);
pLookBack = Param("Look Back", 63, 20, 262, 1, 0);  // Alternate time for EMA Respect

vDesiredEMA = EMA(C, pDesiredEMA);

vCaboveEMA = C>vDesiredEMA;  // Generate array with status

vSumAll = Sum(vCaboveEMA, LastValue(BarIndex()) -1 - pDesiredEMA);  // Sum must exclude the undefined EMA calc space
vSumLookback = Sum(vCaboveEMA, pLookback);  // Sum over Alternate time for EMA Respect

vPercentageAll = vSumAll/(LastValue(BarIndex()) - 1 - pDesiredEMA)  * 100;  // % for All bars, Excluding undefined EMA calc space
vPercentageLookback = vsumlookback/pLookback * 100;  // % over lookback

Filter = (vPercentageAll > pDesiredPercentage) OR (vPercentageLookback > pDesiredPercentage);

``````

Hope this helps.

It is worth noting that cumulative sum of some condition is better written this way:

``````m = EMA(Close,desiredEMA);
count = Cum( Close > m ); // gives array output
``````

if you need just one last value then:

``````m = EMA(Close,desiredEMA);
count = LastValue( Cum( Close > m ) ); // gives last value of cumulative sum
``````
