Hi, wich is the easiest way to calculate how many items are sored in a vars variable?

Thank you

Hi MatPed. See series in the manual. When you create a vars with a series(), the 2nd parameter is the # of items; or if left out it defaults to LookBack. Is that what you're asking?

HTH.

... not exactly, I' d like to know how many data have been stored in the vars, not the size

What do you mean by "how many data"? Each run() stores a new value, so you mean the # of run() calls = the number of bars (up to the size you defined, then the oldest value is discarded)?

ok

vars thePrice = series (price());

or something like that...

is there any way, without taking track with an external cointer, how manu values have been stored in the array at a certain time?

For your example of series(price()) (where length is omitted and therefore defaulted to LookBack), min(Bar,LookBack)?

I think it will always be equal to LookBack

Yes, you are right. Thank you Ddlv and boatman!

Hi boatman. Not necessarily:

a) I believe MatPed was asking about the number of values stored so far. On the 1st bar that would be 1, 2nd bar 2, etc. Up to the defined length. Thereafter length.

b) length defaults to LookBack, but can be set to anything. If you create a series of length 2, then on the 1st bar 1 value has been stored; thereafter only 2. Similarly, if length is >LookBack then more than LookBack values eventually get stored.

HTH.

DdlV, yes you are right, but I guess the boatman was right too.
If you store the price() in vars for sure the analysis wil not start unless the lookback period is passed. So the number of items stored in the vars will be always equal to lookback.
If the value are not prices but other numbers The issue could be solved initialing all the vars with a predefined value. So counting the number of significant valus stored will be an easy loop.
