There is no limit to the number of intraday trading of futures contracts, because the T+0 trading system can increase investment opportunities and has the function of error correction. As long as you have a sound trading plan, you can combine market band operations many times. However, intraday trading should not be too frequent. Considering the fault tolerance rate of intraday trading, it is enough to operate two or three times a day to avoid the loss of income. However, futures trading is limited, that is to say, a single variety contract has at most one position limit, as long as it does not exceed this position limit, it can be traded normally.
