Different trading goals require entirely different methods and observation periods. For spot trading, you certainly wouldn't refer to a five-minute candlestick chart to decide on buying or selling; you usually need to focus on at least a four-hour chart or even higher timeframes such as daily charts. At this point, you need to consider what method you are currently using for spot trading. Do you have a mature trading system to support it?

Now let's talk about contract trading. What strategy do you use for trading? Which time period do you primarily refer to for market trends? If there is no clear method and you are unsure of when to go long or short, and you do not have a clear understanding of the trading timeframe that suits you, then even with ample funds, it will be difficult to maintain a long-term presence in the market. Therefore, the true cost of trading has never been the profit or loss of a single trade, but rather the ongoing process of learning and enhancing your trading knowledge.
