VPA - 5.0

2021年9月3日

This is a upgraded version of the vpa analysis script which basically implements Volume Spread Analysis (aka Volume Price analysis). It has been rechristened as VPA 5.0 to be inline with version released for Amiboker package so that all future upgrades will go hand in hand. All most all featured of the Amibroker version has been incorporated in this version. Some important additions are as follows
1. A status window for the bar and Trend Description added. No need to plot the trend bands or additional trend Indicator any more.
2. The most important upgrade would be the addition of a Alert window which provides description of the VSA signals. It is also a log window which provides up to 10 last signals
(Credits to Quantnomad for this wonderful piece of code. This feature is an adaptation of his public code)
3. Added facility to plot EMAs / PEMAs with changable parameters
4. Added facility to plot VWAP
5. Facility to switch on and Off the VSA signals. Also tool tip provides description of the signals
6. Facility to plot Resistance and Volume Lines (Credits to @margepadu)

Hope this script will be helpful to everyone. Please do provide your feedback and suggestions for improvements
