## Yahoo Plugin

### Description:

Historical and 10 - 20 minute delayed quotes from all yahoo supported exchanges are available with this plugin.

Adjustments: Yahoo provides an Adjusted Close column in its data, scaling prior closing prices to the most recent price based on stock splits and dividends. For example, if a 2-for-1 split occurs halfway through the data, the Adjusted Close price from before the split will be half of the Close price. If the Adjustments option is checked, the plugin will calculate the factor between the Close price and the Adjusted Close price and apply it to Open, Close, High, Low, and Volume. It divides the prices and multiplies the volume, so in any case Close x Volume is the same as before the conversion. This allows you to display continuous graphs and analyze the movement of an issue without large jumps due to stock splits, although the caveat is that absolute prices are a factor different from what occurred on the exchange that day. Having said that, factoring for historical events in this manner is a common approach for visually graphing stock prices.
