Hi,
If I left open GoCharting for hours, 4H time frame, and then the page is reloaded, the last closed candlestick (pointed with a green arrow in the screenshots) change its size. Some times changes its color (green to red or red to green). See atached screenshot, first one is the original, second one, the same candlestick changed its size after the page was reloaded.
