I just want to say that I was greatly impresed to find the last's issue of S&C Traders Tips Backscan in the Snapsheets Library all ready to be used....That's wonderful. ;) that makes Backscanner worth its while compared to its competitors.... no coding or cutting and pasting, congrats to the Worden family.
One quick question though ...how do I add conditions to these particular scans or am I not allowed to.
Thanks in advance

If you right click on any condition in the BackScan you should see the ability to add a AND, OR or SEQUENCE condition.

Are these equations available in telechart format?
A % true for an mav cross up and a % true for a
mav cross down..
(I'm assuming this is the dual moving average cross
indicator)
Thanks

diceman,
Let's take a look at the example given in the magazine. There's a red 20-Period Simple Moving Average of Price and a yellow 30-Period Simple Moving Average of Price. The idea is that "Tomorrow's Close" will cross through Price before the 20-Period SMA and 30-Period SMA cross, getting you into or out of the trade a period or so before the Moving Averages themselves (assuming you are using this as a signal).
Tomorrow's Close can be plotted on the Price Pane fairly easily as a Custom Indicator:
Select Chart Template | Add Indicator | Indicator.
- Visible: Checked
- Center Zero Line: Unchecked
- Plot using price scale: Checked
- Smoothing Average: 1
- Average Type: Doesn't matter (because the Smoothing Average is 1)
- Indicator Formula: (20 * (30 - 1) * AVGC29 - 30 * (20 - 1) * AVGC19) / (30 - 20)
Tomorrow's Close will mostly plot beyond the visible portion of the Price Pane, but that doesn't matter because we are only interested in when it crosses Price. When Tomorrow's Close crosses up through Price, it is predicting that the 30-Period SMA will cross up through the 20-Period SMA and when it crosses down through Price, it is predicting that the 30-Period SMA will cross down through the 20-Period SMA.
The following will spike up when Tomorrow's Close is predicting the 30-Period SMA crossing up and spike down when Tomorrow's Close is predicting the 30-Period SMA crossing down.
Select Chart Template | Add Indicator | Indicator.
- Visible: Checked
- Center Zero Line: Checked
- Plot using price scale: Unchecked
- Smoothing Average: 1
- Average Type: Doesn't matter (because the Smoothing Average is 1)
- Indicator Formula: SGN((20 * (30 - 1) * AVGC29 - 30 * (20 - 1) * AVGC19) / (30 - 20) - C) - SGN((20 * (30 - 1) * AVGC29.1 - 30 * (20 - 1) * AVGC19.1) / (30 - 20) - C1)
This can be converted to a Boolean formula by adding >, < or <> to the formula depending on if you want spikes for crossing up, crossing down or crossing either way (and using the formula in a Custom Percent True Indicator).
