I am still very much in the "discovery" phase with BullCharts - but I like everything about it and what it offers to "seekers of a better way" I really need some assistance and guidance on how to develop a Scan based on the Klinger Oscillator. My thinking is that to trade, the stock needs to be above a 89 EMA and then a buy occurs when the KO turns up from under the "0" line and crosses it, whilst the blue signal line crosses ( or has crossed) above the dotted trigger line. Not sure if I am calling these lines by their correct name - hence the line and the dotted line is used. The above is based on trading the long side - reverse it for the short trading side. Any assistance ( especially from BullCharts) would be most appreciated.

Hi Rhubarb, The first criteria was easy. It reads: Close is greater than Moving Average - Exponential (Close, Expontential, 89, 0, 0) Result #1 The second criteria was not so easy, but I think I managed to do it. It reads: Kilinger Oscillator (13) Kilnger Osc is greater than Kilinger Oscillator (13) Signal. The key to setting up the 2nd criteria was that under parameters you can select the Oscillator itself or the signal line. I have attached a screenshot and a copy of the scan I made, regards, Simon (P.S. As always it amazes me at the intuitiveness of this program) Download the scan by clicking here ->> http://www.bullcharts.com.au/forum/uploads/SimonSavva/2004-09-26_203305_klinger.sc - 2004-09-26_203305_klinger.sc

Yep, Simon's reply looks pretty good. Though it doen't cover the zero
line criteria you mentioned. So do the two he entered, then add: * Klinger Oscillator (13) Klinger Osc crosses above 0. Also, for the second criteria he listed, you might consider changing "greater than" to "crossed above" depending on your needs. If you find that these scans don't return any results, you can change the "condition" field to "Any time in the last 3 days" (or similar). This is especially important if you're looking for scanning on two different crossovers - otherwise if they don't happen on exactly the same day then it won't get matched. |

G'day Simon and Peter, Many thanks for your prompt helpful suggestions - I will now have a go at it - this is an excellent example of how help from our fellow members ( and staff) will ensure the ongoing success of this great program.

Well, I was able to get the Scan operating, just fine....EXCEPT.....I overlooked an important requirement......I was looking to do this on a "Weekly" time basis - not daily. I have noted that in other scans which are produced for weekly charts - they make a note of this somewhere in the "works" Peter, you may be able to direct me on this important modification.

My opening comment to this subject was that I was in the "discovery" mode. I just discovered how to do what I wanted - change the opening scan requirement from "Daily" to "Weekly" - problem solved.....thanks again.

This seems like a good time to show off another BullScan feature: Say you're doing a weekly scan, and you run it on Thursday afternoon. You can choose to either scan at the close of the last week, or include the current week in progress as the last data point for the scan. Eg: You might want something along the lines of "the volume for the week currently in progress must exceed the average volume by 100%", etc. Tick the "Include Incomplete Period" checkbox below the period dropdown to access this feature. |

I'm trying to write up a scan.. Anyone know what the definition is of a bar? Is it a price? |

A bar is a generic word for a data point. Referring to bar charts which is a common chart. So if weekly then the bar represents a week etc. If we had only daily data then daily would be clear. However with weekly etc we choose a generic word. -------------

Yes, "data points" is the best synonym for it. Or for a daily scan,
maybe "trading days". The word is derived from bars on an ohlc bar
chart. For example, you can create the scan "Volume is greater than Volume 5 bars ago". If you set the scan period to "daily" then volume is compared to 5 trading days ago, or if you set the period to "weekly" then the volume is compared to 5 weeks ago. |
