Many exchanges are adapting twenty-four hour trading. In an effort to anticipate possible dilemmas posed by new hours in a world-wide market, We have designed holidays by exchange so it can operate without primary or secondary holiday filtration. To set an exchange to no holiday filtration, follow these steps: 1. Click on the Holiday List field. 2. Select No Holidays from the Holidays List menu. The Holiday List menu disappears; no holidays are excluded from intraday charts on instruments from the exchange. The No Holidays list overrides the Global List; therefore, no holidays will apply to an exchange to which the No Holidays list is assigned.No Filtration
