Please indicate where we can find a list of all EFS reserved words and their meaning.

Hello mbuta,

eSignal Formula Script uses JavaScript 1.5. You can find all the reserved words here.

Thank you Jason,

What about the EFS specific Reserved Words,like BARSTATE_ALLBARS
and many others?
NOTE: Please ignore my email today. David answered that question.

Hello mbuta,

BARSTATE_ALLBARS is a returned string associated with the getBarState() function. There are three states that can be returned:

BARSTATE_ALLBARS - Returned when an advanced chart is instantiated for the first time.
BARSTATE_NEWBAR - Returned at the beginning of a new bar.
BARSTATE_CURRENTBAR - Returned for each tick intra-bar.

You can use getBarState() to control what happens with your formula for these three states. For example:

function main() {
    var BarState = getBarState();

    if (BarState == BARSTATE_ALLBARS) {
        // do something only once at the beginning
    }

    if (BarState == BARSTATE_NEWBAR) {
        // do something only when a new bar starts
    }

    if (BarState == BARSTATE_CURRENTBAR) {
        // do something for every tick
    }
} 

There isn't a single list that contains all the EFS specific words like these states above. Is there a specific problem you are trying to solve? If you are just trying to learn more about writing EFS formulas I would recommend reading our guides for developing eSignal Indicators and back testing Strategies. If there are other specific key words you want to learn more about, you could do a search for that word and find other threads containing those words. Hope this helps.
