EPREM A0 versus $PREM problems w/my EFS

[fish7]

I have a little EFS script I wrote that gives an audible alert when the high/low of the current bar goes above/below a set threshold (variables: vPREMbuy and vPREMsell). It works flawlessly for $PREM on a 1min chart. However, when I use the symbol EPREM A0 instead, it does not trigger at all, desite the prices obviously crashing the trigger levels.

Why is this happening?... is there a way around this?

The basic main code is like this (very simple):

if (getBarState() == BARSTATE_NEWBAR) {
bAlert = false; }

if (high(0) >= vPREMbuy && bAlert==false) {
bAlert = true;
Alert.playSound(WaveFilePREMbuy); // Play the BUY audible
}
else if (low() <=vPREMsell && bAlert==false) {
bAlert = true;
Alert.playSound(WaveFilePREMsell); // Play the SELL audible
}

That is because the two symbols are in different price ranges.
For example 800 with $PREM (or $EPREM) is equivalent to 8.00 in EPREM A0.
To verify this insert an addBand(vPREMbuy, PS_SOLID ,2 ,Color.red ,"vPREMbuy"); in the EPREM A0 chart and see where it draws

To make the efs work indifferently with either symbol you could just add the following to your script
Alex

if(getSymbol()=="EPREM A0"){
    vPREMbuy = vPREMbuy/100;
    vPREMsell = vPREMsell/100;
}

thnx

Alex,

Thanks for your reply... that fixed it.

What threw me is that the Y-axis is the same for $PREM as it is for EPREM A0 ... despite the fact that the data for the two is different by a factor of 100.

THnx again!
