ref() and getValue()

[kztd]

Im having trouble understanding the difference between ref() and getValue.

I would like to know if the high for the current bar is >= the high for the previous 10 bars.

When i caclulate

high() >= Highest(10, high())

Highest(10,high()) seems to include the current bar.

In Metastock, I would write ref( Highest(10, high()), -1) , but the documentation for ref() has no example like that.

I see that getValue has a 'nOffset' parm but I doesn't look like I can put Highest(..) as the bar type.

In eSignal ref() is used to retrieve historical values of an item in the return statement.
To answer your question highest() does include the current bar in its calculations. The solution to what you are trying to do is shown below

var HighH = highest(10,high());
if(high(0) > HighH.getValue(-1)){
//etc
}
