Recently, the price of Ethereum has fluctuated dramatically, once surging to around 4957 before retreating. In this kind of market, operating with a full position carries great risk and can easily trigger a stop loss. In contrast, the strategy I use combines small and large positions, which has proven effective. Small positions are used to test the market, and once a correct judgment is made, I increase the position to enter and exit quickly, securing profits in a timely manner.

The market may challenge the 5000 level tonight. I plan to remain cautious and keep over 600 in margin in the contract account, setting the liquidation point at 5150. Even if liquidation occurs, the loss will be within a controllable range.

Looking back at last night's trades, although the initial judgment was correct, I failed to take profit in time. A position with a margin of 1000 could have made a profit of 1000, and there were also over 700 in floating profits from subsequent trades, but unfortunately, I couldn't lock it in. The lesson is that when there are floating losses, it's not advisable to increase the position; I have made this mistake many times.

Overall, in such a highly fluctuating market, flexibly adjusting positions and strictly executing take profit and stop loss strategies are essential for steady profits. Overconfidence or emotional trading often leads to unnecessary losses. Staying calm and strictly adhering to trading discipline is the key to surviving in the market in the long run.
