A bit of a strange name, I admit.. Here is the rationale behind it: if I screen for BB with 2 std deviations, then I will get 95% of the price action between these bands. If I add a BB with 3 stddev's, then I will catch the remaining 5% of the price range, thus the one that can be qualified as "extreme" . Finally, if I look for candles BETWEEN the upper BB's with 2 and 3 stddev's, I know that these prices will be likely to change, and will probably head down. The price move down is confirmed (in my opinion) if the next complete candle drops below the BB 2.If that condition is met, go short. I didn't try it out yet in real trading on stocks but I gave it a try on FX pairs with hourly charts and made a nice profit already today.( How I wish I could scan realtime FX. Any suggestion is welcome)
So here it is:
Fetcher[
/* Bollinger extremist Short Finder*/
fetch stock where close is between 15 and 100
and volume(60) is above 300000
and price open of yesterday is below the upper bollinger(20,3.0)
and price close of ofyesterday is above the upper bollinger(20,2.0)
]


Ideally, I would like to see the situation:
1. where a complete candle is between Upper BB2 and BB3,
2. and the next complete candle is below the Upper BB2.
3. Stochastics is above 80(announcing a downturn)
4. The price made a fairly steep upward slope in the last 5 days or so.
A similar approach for a "long" filter" would also work. Alas, writing code is not my strongest side... So any help would be highly appreciated.
Regards, Ludo Willems

Hi Ludowillems
I'm a newby and need to know how your trade your Short Term Pops filter. I love the filter, but the results of the screen change about an hour after the market opens. By that time it's too late to catch the big moves.
Are you trading this off of the screen from the previous day's close or of f of the next day mid-morning screen after the market opens?

Thanks!

to lynnchismod: I check my filter in the evening and trade from the market open next morning. That evening, check again, have a look at the technicals and keep it or sell it next morning.

Hello, lynnchismod or ludowillems

I have been trying to find the "Short Term Pops" filter that lynnchismod talks about above in the public filters but no luck. Could you point me to it?

Thanks

Hello all,
I made some changes to my "Bollinger extremist finder". I am looking for bullish stocks from which the candles position themselves between Upper BB (20,3) and Upper BB(20,2) for the last x days. Although the debug screen shows all green OK's, the charts show a different picture. Give it a try and please feel free to comment my mediocre programming skills.

fetch stock where close is between 15 and 100
and volume(60) is above 300000
and price has been increasing for the last 5 days
and price is below the upper bollinger band(20,3.0) and above the upper bollinger band(20,2.0) today
and price is below the upper bollinger band(20,3.0) and above the upper bollinger band(20,2.0) 1 days ago
and price is below the upper bollinger band(20,3.0) and above the upper bollinger band(20,2.0) 2 days ago
and draw bollinger bands(20,3)
and draw bollinger bands(20,2)
and draw bollinger bands(20,1)
and RSI(10) is above 70
