Before the price is determined, shouldn't we first set a bidding range? Then, as the time approaches, we can adjust the order size based on the actual situation. For example, if $BTC is currently quoted at $1, the original plan for a position of 600 units might not be applicable, and adjusting it to around 60 units on the spot would be more flexible. This way, you can lock in the main risks without being overly heavy-handed. When the market is volatile, this kind of phased flexible strategy is often more effective than rigid plans.
