A market ‘gapping’ refers to the price movement of an asset, i.e. currencies, stock indices, commodities, etc. during a period where no trading has occurred.
Gapping in the market is seen as the difference in price of an asset between its closing price at the end of one trading period and its opening price in the next trading period; they typically occur overnight or over the weekend. On occasion, gaps can also occur over shorter time frames.
