DescribeSpotPriceHistory

Describes the Spot Price history. The prices returned are listed in chronological order, from the oldest to the most recent, for up to the past 90 days. For more information, see Spot Instance Pricing History in the Amazon Elastic Compute Cloud User Guide.

When you specify a start and end time, this operation returns the prices of the instance types within the time range that you specified and the time when the price changed. The price is valid within the time period that you specified; the response merely indicates the last time that the price changed.
