Volume Weighted Real Relative Strength (RS/RW)

dealsatm 已更新   
Volume Weighted Real Relative Strength (VRRS) measures the relative strength of a tickers vs. a benchmark ticker for the market, i.e. $SPY, and a benchmark ticker for the sector it is in. The calculation of VRRS is done as follow:

VRRS = * VolWeighted * 100

Close is Close price
smaClose is the last simple moving average value.
Ref is Reference ticker
VolWeighted is the volume weighted factor and is defined as (smaVol_short / smaVol_long); where smaVol_short, smaVol_long are the simple moving average of volume calculated for a short period (i.e. 21 period) and long period (i.e. 5 days), respectively.

1. It can show two VRRS, one calculated against a market benchmark (i.e. $SPY) and one for a sector benchmark.
2. It shows also the bar plot of the benchmark ticker.
This update:
- Updating default value
- Cleaning the code
- Using better default color

In previous description, the formula was cutoff. It should be read
VRRS = ( (Close - smaClose)/smaClose - (RefClose - RefsmaClose)/RefsmaClose ) * VolWeighted * 100
Fix bug for accurate reference plotting
This update includes
  • Fix bug on displaying SPY intra day change
  • Add change rate of VRRS. This measure the rate at which the VRRS changes from bar to bar. It is calculated by using linear regression of the last number of bar (set by user). The Certainty measures how good this calculation is. 100% means completely linearly growth.
  • Select sector automatically for sector VRRS
Add option to disable/enable Auto Sector Selection
  • Volume Weighted is now optional
  • Faster loading
Add comment
Fix typo
Improve loading time
The automatic option to select sector reference causes about 5-10 second delay on the first load. I am still trying to find solution for it. If user does not want this option and want to do manual sector selection (much faster), please do the following
  • Comment out line 130 (add // at the beginning of the line)
  • Uncomment out lines 132 and 133 (remove // at the beginning of the lines)
  • Save the code (Ctrl + S)
