... OLang solution GotHi = false for N = 0 to 19 if H[N] > HHV(260)[N+1] then GotHi = true next N BUT ... since "false"=0 and "true" = -1, we can express this as the sum of 20 tests (ie 4 weeks) Sum((H > HHV(260)[1]),20) < 0 ----------------- OBV higher than 6 months prior: OBV() > HHV(OBV(),130)[1] ----------------- Your Keltner channel = EMA(20) +/- 2*ATR(10), so, Price between midline and lower: EMA(20) - C >= 2*ATR(10) ----------------- I set up these three rules in an OScan of All US Stocks (11k symbols), and there wasn't even ONE symbol that passes all the tests So your rules might have to be loosened up a bit. For instance, if you want the stocks for which any TWO of the three rules are true, you can do this: ( EMA(20) - C >= 2*ATR(10) ) + ( OBV() > HHV(OBV(),130)[1] ) + ( Sum((H > HHV(260)[1]),20) < 0 ) <= -2 ... which gives 162 hits [Edited by Jim Dean on 4/8/2014 11:29 AM] | ||

The 52 week high within last 4 weeks is not bringing up any stocks for me at all. Any solutions? Jarrod | ||

Note: these scan rules are GOOD ONES to learn from. They utilize several tricks and techniques that the majority of OT users are unfamiliar with: 1. Function calls that specify a function as the dataseries instead of just price 2. Function calls that use a Boolean result as the data series 3. Use of the Sum function to check for a condition during a time window 4. Math operations (addition,here) on Boolean results in a formula | ||

( EMA(20) - C >= 2*ATR(10) ) + ( OBV() > HHV(OBV(),130)[1] ) + ( Sum((H > HHV(260)[1]),20) < 0 ) <= -2 The part I corrected is changing the last-line's ">0" to the correct "<0" shown above. This is btw a set of conditions that don't occur very often, even when applied to All US stocks. If you want to "play" with this formula a bit, then you might loosen it up to give you more hits: ( EMA(20) - C >= ATR(10) ) + ( OBV() > HHV(OBV(),30)[1] ) + ( Sum((H > HHV(60)[1]),10) < 0 ) <= -2 The formula in that form says to show stocks for which ANY TWO OF THE THREE RULES are true. Change the final -2 to -3 to force all three rules to be true (like using "AND's" instead of plus signs), and change it to -1 to allow a pass if any one rule is true (like using "OR's" instead of plus signs) As I said earlier, this is a VALUABLE example to study, for anyone who wants to be a "power user" for OmniScript. The "boolean math" is being used not only in the combination of the three distinct rules, but also it's being using in the "Sum()" statement ... adding up ten successive instances of boolean tests.

Sum( ( H > HHV(250)[1] ),5 ) < 0 However it displays green only if the stock in question has made 52 week high on previous day. If it made 52 weeks high on any other day during previous 5 days it doesn't show green but shows yellow. I think it's a bug. | ||
