Updated 16th February 2015 : Zscore_v3
1. Added code to prevent 'out of valid range error' (picked up by Harry - thank you).
2. Changed condition for permission bar coloring.
3. Enabled option to show 1st Std Dev line.
4. Minor visual enhancements and tidied up the code.
For use in sideways or range bound markets.
You can save a few bob if you don't want to pay for a custom profile tool.
The z-score is used to compute the probability of occurrence of a value in a particular normally distributed range OR shows how many Standard deviations away from the mean is a value. If a value is 2 std dev from the mean and you have a nearly normal distribution then 95% of values within that distribution lie above/below your current value in other words there is a good probability that price will revert to the mean and this could be good place to look for a trade back to it or beyond it.
I have shown the volume profile for reference but you can see that this range is normally distributed.
The z-score indy is set to the range of your distribution in ticks. The yellow areas are turning points 2 std dev from the mean and offer the highest probability trades with the lowest risk but the red area turns out not to be worth trading and the z-score helps you stay away from the ambiguity this price action depicted in real time. (HL followed by a LH and then another HL).

Stocks either go up or down. The degree (measured as standard deviation) at which the trend occurs varies by period.
Closing price and not price change is typically used to calculate standard deviation (or dispersion from mean). However, using the standard deviation of closing price does not illustrate price movement from mean. Therefore, a price change percentage of 0% is your staring point.
The equation below will provide a "number" indicating how strong a trend is. The number is the price change per standard deviation for the given period. It works well on a list of stocks that is sortable.
A stock with a strong upward trend will have a higher value and vice versa in a down trend.
This is a modified z-value calculation using zero as a starting point.
