Hi Joe - done. Good suggestion. I'm new to this whole group thing.

That way we could all get to it and use it to augment the documentation of the new plug in.

Hi JD, Thanks for replying to both of my posts. I put together a data map of the QP3 data that can be accessed from AB. I posted it on this board under "GetExtraData Map" about a week ago (I think). I like your functions below and I'll give them a shot tonight. I think I've come up with a solution to getting the EPS and Sales numbers out of the array, but the further back in time I go the more discrepencies I get between what I return and what SPP reports. Have you noticed any discrepencies between what you get and what SPP reports? I hesitate with solutions that look back in
time a certain number of days, as your code seems to suggest, only because most companies don't seem to report very consistently. Then again, many of the companies in the SPP database haven't reported for several quarters, many for several years. I've coded to exclude those stocks from my exploration, but maybe your code avoids that? Jeff

awhile back which demonstrates an alternative non-looping way to look
back into the array based QP data fields that should only change by
quarter:
THOUSAND = 1000;
MILLION = THOUSAND * THOUSAND;
function getSalesMrq() {
return GetExtraData("Sales") * MILLION;
}
function getEPSMrq() {
return GetExtraData("EPS");
}
function
getSalesTtm() {
//Cycle through last 4 quarters and add up the getSalesMrq for TTM
qtrDays = 260 / 4;
salesMrq = getSalesMrq();
return salesMrq + Ref(salesMrq, -1 * qtrDays) +
Ref(salesMrq, -2 * qtrDays) + Ref(salesMrq, -3 * qtrDays);
}
function getEPSTtm() {
//Cycle through last 4 quarters and add up the getSalesMrq for TTM
qtrDays = 260 / 4;
epsMrq = getEPSMrq();
return epsMrq + Ref(epsMrq, -1 * qtrDays) +
Ref(epsMrq, -2 * qtrDays) + Ref(epsMrq, -3 * qtrDays);
}
