Understanding the MAX function

[Andy73]

Hello there

This probably sounds a silly question, but I'm looking at this line of code within the parabolic indicator script:

Value.Set(xp + (longPosition ? -1 : 1) * ((MAX(High, CurrentBar)[0] - MIN(Low, CurrentBar)[0]) * af));


so my queary is.. doesn't this

MAX(High, CurrentBar)[0] just mean High;

and this

MIN(Low, CurrentBar)[0]) just mean low:

Thanks in advance....... Andy

MAX(High, CurrentBar)[0] means the maximum of the high values of the last "CurrentBar" bars (equivalent for MIN(Low, CurrentBar)[0]))

Thank you for the quick response, but I'm a little confused, doesn't currentbar mean the actual currentbar in progress?


Here's the section of code it's from

if (CurrentBar < 3)
return;
else if (CurrentBar == 3)
{
// Determine initial position
longPosition = High[0] > High[1] ? true : false;
xp = MAX(longPosition ? High : Low, CurrentBar)[0];
af = Acceleration;
Value.Set(xp + (longPosition ? -1 : 1) * ((MAX(High, CurrentBar)[0] - MIN(Low, CurrentBar)[0]) * af));
return;


Thanks

Right, thus code below calculates the max of the highs of all bars seen so far.

Thank you again for the lightening quick response, just so I can get my head around it. It's basically saying the highest high of the first 3 bars on the chart to get the indicator underway... is this correct?

Thanks

I have not read the thread but...

MAX(High, 3)[0]

would return the highest high value of the last three bars.
