Scanner Issue...

[netarchitech]

I have an issue with the TOS Scanner...Essentially, no matter what I do, the Scanner returns the same result set...and none of the returned results meet the criteria specified...

Given the following setup below:

Here is a sample of the result set:

Here is the custom script I am scanning with:

def length = 2;
def price = close;
def averageType = AverageType.WILDERS;

def NetChgAvg2 = MovingAverage(averageType, price - price[1], length);
def TotChgAvg2 = MovingAverage(averageType, AbsValue(price - price[1]), length);
def ChgRatio2 = if TotChgAvg2 != 0 then NetChgAvg2 / TotChgAvg2 else 0;

def RSI = 50 * (ChgRatio2 + 1);

plot scan = RSI < 10;

Am I missing something, is the Scanner broken? Any help would be greatly appreciated...Thanks in advance...

There is a disconnect between the script that you posted in your thread and the script that you have stuffed into the scanner.
They are not the same.

And FYI, the script in the scanner references an aggregation period which generally upsets the Scan Hacker.

Hi @MerryDay : Thanks for your reply and pointing out the coding discrepancy...The screenshot of the scan settings reflects an earlier iteration of code that I corrected after receiving the "Secondary Aggregation not allowed" error...The script posted above ran fine...Unfortunately, it just is not returning the correct results...I must say I'm at a loss to understand what appears to me a rather simple scan...

In any event, I am going to run it again, for the umpteenth time and see what happens...I'll continue to update the thread as the events unfold...

Thanks again for the support...I really appreciate it!

Have a great day

Have a great day

have you changed the aggregation time , from month, to something else, to see if the output is different?

if you are running this scan many times, i hope you are changing settings, and seeing changes in the output.

if you aren't seeing any changes in the output, then maybe something isn't set right. that is the time to remove your scan script and replace it with something simple., like close < 20, and see if the output changes.

the next thing to try is enabling scripts in the scanner.
in your image , 'none of the following' is displayed in the header, meaning scripts will be ignored.

@MerryDay @halcyonguy :

Thank you for your responses and the support you've provided...I did finally stumble across the solution...Unfortunately, I did not see your post, @halcyonguy, regarding the "None of the following" condition grouping until after a lot of trial and error and frustration...

So it turns out that the study was somehow placed in the wrong "None of the following" Condition Grouping...see below...

TOS was scoping out the results I was looking for in order to satisfy the condition! As a result, all I had to do was to move the RSI script to the "All of the following" Condition Grouping and all is well now...My father gets the scan results he was looking for and I got to learn something new

Thanks again for your time, support and attention to this issue...It is greatly appreciated!

Good Luck and Good Trading
