No 1 day candle option in Screener

Hi I am a strategy developer

I need to scan for gap up (gap between yesterday’s closing price and today’s opening price) and alert when Last Traded Price comes down to yesterday’s close price filling the “gap up”.

eg.

OPEN>REF(CLOSE,1)

AND

LAST<=REF(CLOSE,1)

but scanner doesn’t have day (only hour and minute is available in “PERIODIC” dropdown menu) candle option. i don’t prefer using expert advisor for this, as i need to open individual chart for each and every stock i am monitoring. Scanner comes in handy, monitoring multiple stocks in a single screen.

Specific to gap up and gap down… can not be scanned…!

GapUP: LOW>PreviousHigh

GapDOWN: HIGH<PreviousLow
