JStockCharts Update- Ease of Movement Indicator

Ease of Movement Indicator (EMV)

Developed by Richard Arms, Ease of Movement (EMV) is a volume-based oscillator that fluctuates above and below the zero line. As its name implies, it is designed to measure the "ease" of price movement. Arms created Equivolume charts to visually display price ranges and volume. Ease of Movement takes Equivolume to the next level by quantifying the price/volume relationship and showing the results as an oscillator. In general, prices are advancing with relative ease when the oscillator is in positive territory. Conversely, prices are declining with relative ease when the oscillator is in negative territory.

JStockCharts provides 14 day SMA of EMV. Users must select a period higher than or equal to 03 month to render this chart type.

Further I have optimized the code of WatchList to ensure more effectiveness of the data displayed in it. for an example I have added a no change color (orange) for two types of changes in closing price. first , If there were no trades for the last trading day or previous trading date for a given counter, there is no point of calculating the change hence such counters rendered in no change color. and second is the most obvious , of which closing prices were same for the two days. 
In the following screen capture HSIG's closing price shows as 0.00 because it hasn't been traded for the last updated trading date. other three counter's are self explanatory.
