To put this simply, traditional technical analysis IS NOT MATH.
When you get into analyzing the data, you start to realize where the problem is.
The data is often normalized by time, not price.
Why is this a problem?
You would have to wonder how different things would be if the data were normalized by price.
The mathematical formulas that you are applying would almost certainly have a better chance of producing some beneficial insight.
This is why technical indicators are more productive on daily charts rather than intra-day charts. Because the price data is ‘more similar.’
When you look at an intra-day chart, you start to realize that the data is drastically different.
What occurs in one 15-minute time interval may not even be remotely similar to what happens in another 15-minute time interval the rest of the trading day.
