 One of the steps in my easy scan is: STOC8.3 <= 40

However, the results of the scan has today's values way over 40.

This has got to be simple.

thanks,

 What plotted stochastics settings are you using on your chart?

 I set up a new easy scan with just the one stochastics check and it seemed to only pick out those that met that criteria.

Then I added a second one that said that the 50-day moving average had to be up.

It looks like these two were not added, but rather or'd. But then the number of hits went down . . . even more strange. Clearly I'm doing something wrong.

 bdavis3,
I can assure you that an EasyScan does not OR the results. An EasyScan always ANDs its conditions. This explains why the number of hits went down. Adding an EasyScan Condition will never increase the number of results.

The most likely issue is related to Craig's unanswered question, "What plotted stochastics settings are you using on your chart?"

STOC8.3 is the SK for a daily Stochastic with the following settings:

- Period: 8
- SK Period: 3
- SD Period: ?
- Average Type: Simple

If the SD Period were five for example, the formula for the SD would be:

AVG(STOC8.3,5)

If we adjust the Average Type to Exponential:

- Period: 8
- SK Period: 3
- SD Period: 5
- Average Type: Exponential

We would get the following formulas instead:

SK:

XAVG(STOC8,3)

SD:

2 * XAVG(STOC8,5) - XAVG(STOC8,3)

 Thanks for the prompt help. It turns out my problem was truly basic. I knew it had to be something simple, because nothing was working as I expected it to.

Seems I have it set to weekly and not daily, ergo, the scans produced output that appeared to be totally out of whack.

I am just starting to use the program and I'm impressed, thus far.

 bdavis3,
I'm happy to read you were able to figure out what was causing the difference.

 A friend of mind gave me these custom indicators that work really well. I was wondering if their was a way to convert the to TC2007.

Strength % ((Bar [Close,D] - Bar [Low,D])*100)/ (Bar [High, D] - Bar [Low,D])

3 DAY Strength % (((Bar [Close,D,1] - Bar [Low,D,1])*100)/ (Bar [High, D,1] - Bar[Low,D,1]) + ((Bar [Close,D,2] - Bar [Low,D,2])*100)/ (Bar [High, D,2] - Bar [Low,D,2] ) + ((Bar [Close,D,3] - Bar [Low,D,3])*100)/ (Bar [High, D] - Bar [Low,D,3]))/ 3

JAYZ OSC (Stochastic[StocK,6,3,3,D] >= 20) + (Stochastic[StocK,6,3,3,D,1] < Stochastic[StocK,6,3,3,D]) + (Stochastic[StocK,10,3,3,D] >=20) + (Stochastic[StocK,10,3,3,D] > Stochastic[StocK,10,3,3,D,1] ) + (MACD[MACD,Close,8,17,8,D] > MACD[Signal,Close,8,17,8,D] ) + (MACD[MACD,Close,8,17,8,D,1] > MACD[Signal,Close,8,17,8,D,1]) + (MACD[MACD,Close,10,22,8,D] > MACD[Signal,Close,10,22,8,D])

I'm not familiar with the language, so the following will be, to a great extent, guesses.

QUOTE (dogstar)
Strength % ((Bar [Close,D] - Bar [Low,D])*100)/ (Bar [High, D] - Bar [Low,D])

The formula would simply be:

STOC

It is a Stochastic with the following settings:

Period: 1
SK Period: 1
SD Period: 1
Average Type: Doesn't matter (because the SK and SD periods are both 1)

QUOTE (dogstar)
3 DAY Strength % (((Bar [Close,D,1] - Bar [Low,D,1])*100)/ (Bar [High, D,1] - Bar[Low,D,1]) + ((Bar [Close,D,2] - Bar [Low,D,2])*100)/ (Bar [High, D,2] - Bar [Low,D,2] ) + ((Bar [Close,D,3] - Bar [Low,D,3])*100)/ (Bar [High, D] - Bar [Low,D,3]))/ 3

I'm guessing the formula would simply be:

STOC1.3

It might be yesterday's value however:

STOC1.3.1

It is a Stochastic with the following settings:

Period: 1
SK Period: 3
SD Period: 1
Average Type: Simple

QUOTE (dogstar)
JAYZ OSC (Stochastic[StocK,6,3,3,D] >= 20) + (Stochastic[StocK,6,3,3,D,1] < Stochastic[StocK,6,3,3,D]) + (Stochastic[StocK,10,3,3,D] >=20) + (Stochastic[StocK,10,3,3,D] > Stochastic[StocK,10,3,3,D,1] ) + (MACD[MACD,Close,8,17,8,D] > MACD[Signal,Close,8,17,8,D] ) + (MACD[MACD,Close,8,17,8,D,1] > MACD[Signal,Close,8,17,8,D,1]) + (MACD[MACD,Close,10,22,8,D] > MACD[Signal,Close,10,22,8,D])

Considering the fact that Simple Moving Averages were used for Stochastics in the first example, I'm guessing:

AVG(STOC6.3,3) >= 20 AND AVG(STOC6.3.1,3) < AVG(STOC6.3,3) AND AVG(STOC10.3,3) >= 20 AND AVG(STOC10.3,3) > AVG(STOC10.3.1,3) AND XAVGC8 - XAVGC17 > XAVG(XAVGC8,8) - XAVG(XAVGC17,8) AND XAVGC8.1 - XAVGC17.1 > XAVG(XAVGC8.1,8) - XAVG(XAVGC17.1,8) AND XAVGC10 - XAVGC22 > XAVG(XAVGC10,8) - XAVG(XAVGC22,8)
