Futures ultra-short-term is not zero stop loss, it will only set the stop loss narrower. If zero stop loss equals no stop loss, it is meaningless to prevent and control losses for futures orders without stop loss. The ultra-short-term stop loss should be set at a narrow stop loss point. Usually, futures short-term orders are charged in a 5-minute cycle or 15-minute cycle, so the general stop loss range will be set very narrow, with a stop loss of 5 to 6 points. You see, if you do futures with a cycle of 1 minute, usually the stop loss may only be in the range of 1 to 2 hops, but a narrow stop loss does not mean that there is no stop loss, and you should also have a stop loss when you do ultra-short futures, because the big decline or rising market also develops from a small decline or rising trend. Therefore, when you open short futures orders or multiple futures orders, you should set stop losses for both ultra-short and overnight orders, otherwise you will do the opposite.
