Problem with bar closure

[julifro]

Hi. I'm a rookie programmer.
I have this code
(Volume[0] < Volume[1])&&(Volume[1] > Volume[2])
The bar that fulfills this condition will be called the Bv
I don't know how to do this now.
If the Low[0] is < Bv then draw arrow
thank you.

Hello julifro,

Thanks for your post.

It depends on what of the Bv bar you are wishing to compare. I'll show a couple of ways.

You could make Bv an int variable that holds the bar number of the latest bar that meets the criteria. You can then subtract the Bv from the CurrentBar to get the bars ago that the Bv was and reference that bars data, for example:

if (Volume[0] < Volume[1])&&(Volume[1] > Volume[2])
{
Bv = Currentbar; // save bar number of the Bv bar
}

if (Low[0] < Low[CurrentBar - Bv]) // if the low is less than the low of the Bv bar.
{
// draw the arrow
}

Alternatively, if all you are interested in is the low Bv value then you could make the Bv a double variable and just store the low of the Bv bar at that point, for example:

if (Volume[0] < Volume[1])&&(Volume[1] > Volume[2])
{
Bv = Low[0]; // save the Bv bar low value
}

if (Low[0] <Bv) // if the low is less than the low of the Bv bar.
{
// draw the arrow
}
