Recently, a certain Perp exchange has come up with a new trick. In addition to the usual deposit and trading volume incentives, they have launched a simple market-making method — just place limit orders to provide order depth to the market and earn points. It sounds not difficult, but to maximize your points, you need to master a few tricks.

First, you need to understand how points are calculated. The core logic is clear: the proximity of your order to the market price, the size of the order, and the duration of the order directly determine how many points you can earn. The exchange divides the distance from the market price into three tiers — A, B, and C. Tier A is 0 to 10 basis points, which grants 100% of the points. Tier B is 10 to 30 basis points, with 50%. Tier C is the farthest, 30 to 100 basis points, with only 10% reward.

It sounds like Tier A is the most cost-effective, but there's a trap in practice: orders placed very close to the market price are easily filled instantly. You might not even have enough time before they get taken, which reduces your points. Tier C is safer, but the reward weight is too low to be ideal.

The truly optimal strategy is to stay in Tier B. For BTC, placing orders roughly around 500 USD away from the market price works well. As for order duration, a range of half an hour to an hour is quite balanced. Of course, if you're a coding expert, you can also develop an automated market-making script to run and automate operations. This way, you can treat market making as passive income and adjust your strategy promptly during market volatility.
