Limit 3 Symbols Per Formula

[mbuta]

Hi,

I modified the OHLC function provided by eSignal to get the previous day close for diferent symbols (see below).
I am calling this function from an other formula. Altgough there are two (2) calls (NQ/NDX or ES/SPX), I get the following message for the line 78 in the called funtion:
" Function..., line 78: The Symbol Lymit (3) for a formula has been exceeded"

Can anybody explain why and how can be corrected?
Thank you.

FUT_SYMBOL = "ES "+CONTRACT_MONTH;

}

var CASH_IDX = close(0, 1, IDX_SYMBOL);
var FUTURES = close(0, 1, FUT_SYMBOL);
var PREV_DAY_CLOSE_IDX = call("MyFunctions/MyPrevOHLC.efs", "Close", IDX_SYMBOL);
var PREV_DAY_CLOSE_FUT = call("MyFunctions/MyPrevOHLC.efs", "Close", FUT_SYMBOL);
var PERCENT_MOVE_CASH = 100*(CASH_IDX - PREV_DAY_CLOSE_IDX)/PREV_DAY_CLOSE_IDX;
var PERCENT_MOVE_FUT = 100*(FUTURES - PREV_DAY_CLOSE_FUT)/PREV_DAY_CLOSE_FUT;

EFS has a 3 symbol limit. However this has been raised to 5 in the latest beta.

I understand the present limitation.

However, if you read the code, I call the function only twice, based on the IF condition in my indicator.

Why is considering ALL the variants of the IF function and considers that I am calling the function four times?
This is not correct and should not happen.

Thank you,
Mihai

You don't really give enough code for me to debug this, I would put in debug statements if I were you to verify that the symbol you think you are using in the called function is really the symbol you think it is.

Hi Spiker and thank you for your help.

I posted the relevant portion of my study, where I compile and select the symbols.
They should be: $SPX and ES M3, or $NDX and NQ M3.
You can check if is done right.

From the OHLC function, I provided the line that generates the error. The entire efs is the same as the "getPrevOHLC.efs" in the OHLC directory, where I made the symbol a parameter. Tha is all.

The point is that, see in my code, I call the function only twice (for the pair of symbols generated), but is gives me the error.
If I delete any branch of the "if" I get no error and it works fine.

Thanks,
Mihai
