The foreign exchange margin is the lowest, that is, the leverage is the largest, but the foreign exchange is foreign, so it is not easy to judge the trend. Futures margin is generally around 10%, which is a little higher than foreign exchange, but the futures cost is lower than foreign exchange and it is easier to operate. Moreover, futures can use capital allocation to increase leverage, and the stock is fully operated, and it is one-way T+ 1, and futures is two-way T+0.
