I want a green bar two days ago followed by two red bars. This isn't returning, say , JOY but I dont see an obvious error
What am I missing?
Fetcher:
close two days ago > open two days ago
open one day ago > close one day ago
open > low
low < close two days ago
low > 20
stocks are optionable
volume > 1000000

General Discussion · Slope number seems wrong

I got a reply from the nice StockFetcher people:
"Thank you for the feedback. The "slope" on StockFetcher is the slope calculated from the "bestfit" line using linear regression:
http://en.wikipedia.org/wiki/Linear_regression
Your example below is more similar to a "rate of change" computation."

These should return exactly the same number but they don't. Am I missing something?

General Discussion · linear regression intercept

kevin_in_ga the description says "The linear regression slope indicator simply computes the slope of the linear regression line. " so one would think the linear regression intercept is available. I know the definition of slope, in this case it's the "rise over run" of the linear regression line. My question was, is the linear regression line available by itself? That would give you the intercept.

The linear regression intercept is used to calculate the linear regression slope but does not seem to be available as a separate indicator. Am I missing something? Any idea how to calculate it?

So what are we looking at here? A MA crossover system?

I want to count how many times a stock has been down two days in a row is the last 60 days , but this doesn't work. Any ideas?
[set {dds, count (close less than close one day ago and close one day ago less than close two days ago,60)}
price greater than 1
add column dds

General Discussion · value uses previous value except at start

I'm trying to write a function that uses the previous value of the function except at the start, when is uses the close (because there is no previous value then). Anyone have any idea how to do this?

Is there a stockfetcher function equvalent to the following thinkscript?
Syntax
compoundValue(int length, IDataHolder visible data, IDataHolder historical data);
Description
Calculates a compound value according to following rule: if a bar number is bigger than length then the visible data value is returned, otherwise the historical data value is returned. This function is used to initialize studies with recursion.
Example
declare lower;
rec x = compoundValue(2, x[1] + x[2], 1);
plot FibonacciNumbers = x;
The example calculates the Fibonacci sequence. Starting from the third bar each following number is calculated as the sum of the previous two numbers while the numbers for the first two bars are equal to one. As a result you will get a plot containing the 1 1 2 3 5 etc values.
