scan for gaps

[apex82]

Does anyone know of any services that allow you to scan for stocks gapping before the open but also include a volume filter?
-Thanks

Anyone know of a free scanner out there for gapping stocks...or a site that just lists a few would be fine as well.
Thanks

Quote from ModulusFE:

Well, maybe. But try this on Yahoo! with 11,000 stocks at once
# Buy if a previous value was below the low Bollinger band and is now above
SET Bottom = BBB(CLOSE, 20, 2, EXPONENTIAL)
SET Top = BBT(CLOSE, 20, 2, EXPONENTIAL)
FIND STOCKS WHERE (((REF(CLOSE, 1) < REF(Bottom, 1)) AND
RSI(CLOSE, 14) > 70 AND VOLUME > REF(VOLUME,1) * 2 AND VOLUME > 100000
AND CROSSOVER(CLOSE, PSAR(0.2, 0.02)) AND CLOSE > Bottom) OR
# Also buy if the close is above the top band plus 2%
RSI(CLOSE, 14) > 70 AND VOLUME > REF(VOLUME,1) * 2 AND VOLUME > 100000
AND CLOSE > Top * 1.02 and MO(CLOSE,7)>75 AND CMO(CLOSE,7) < 60)

yahoo allow you to receive quotes for 200 tickers at once. with filters you post above applied, list will be much smaller. I’m not saying it will be instant, but it can be pretty quick. i would say 10-20 sec max. not so bad for web service. If you are dirt cheap and can code it by yourself-it’s can be decent solution

Thanks Bob111

I was thinking about a site I could go to pre-market that would list some.

i use YahooFiance for premarket trading and gaps. cheap, but you can only have 200 stocks per group, to filter.

Hi PatrickQ

Do you just use their free stock screener or do they offer a service?

Thanks

 

[PatrickQ]

it is a service, for $9.99 a month. i simply build out portfolios and include Pre Mkt Chg & Pct - and I look at the Volume of premarket, and have a column for Avg Vol (3m) for comparison. it is part of my routine, in the morning to scan my portfolios LOOKING to see IF I missed major news, or sympathy moves. I look at NYSE and NAZ stocks, both.

Where can the documentation for accessing the market tracker web services api be found? I don't see anything at yahoo for accessing this service from code. All I see is using there provided client software.
