BoolSeries

[shawnkm]

I'm using a multi-time frame and BoolSeries and trying to build a strategy.

Is there any way to say did the BoolSeries trigger within the last ten bars on a different timeframe?

Example:

5 minute chart upTrend became true on current bar, look back to see if upTrend became true within the last 10 bars on 15 minute chart.

Thank you.

Hello shawnkm,

You would need to add the secondary instrument series to your script. Then sync the boolseries with this added secondary series so there is one slot for each secondary series bar in the boolseries.

Below is a link to an example of this.

I understand adding the secondary instrument series. And I understand the sync with the boolseries.

What I dont understand is the code needed to test for true within the last 10 bars... ie. not just 10 bars ago... but was it true for any of the last 10 bars.

Can you please provide the code needed for this?

Thank you.

Hello shawnkm,

You would need to loop through the last 10 bars and test for a true.

bool trueFound = false;
for (i = 0; i < 10; i++)
{
if (MyBoolsSeries[i] == true)
{
trueFound = true;
}
}

if (trueFound)
{
Print("MyBoolSeries contains a true value within the last 10 bars");
}
