postMain() ?????

[wombat953]

Is there such a thing as a postMain() function, which will execute once only, after the last bar has been pocessed?
Thanks

Hi,

There is a postMain() but my understanding is that it is run when a formula is removed or reloaded...

The concept of a "last bar" is interesting when thinking about RT mode. In theory, there will never really be a last bar, but I suspect you mean the newest bar on the chart. If this is the case, you can use getCurrentBarIndex() and look to a index of 0...which means you are processing the newest bar on the chart.


var nIndex = getCurrentBarIndex();
if (nIndex == 0){ // At the latest bar
do stuff
}

Hope this helps,

Garth

Thanks Garth - I was wondering what the simplest way to close a file was. If main() is executed once for each bar, then I ceratinly wouldn't want to place it there if I am reading a file, so I turned to thinking about a preMain().

Yep, good thought. postMain() is the way to go. I have seen some studies that open and close the file on each tick, but that hardly seem the correct thing to do.
