Recently, I have been delving into the Opinion project, especially during its platform activities. Through practical operations, I have accumulated some trading insights that I would like to share with everyone.

Speaking of trading costs, many people may not fully understand Opinion's fee structure. On this platform, trading fees are only charged for market orders (Taker side), while limit orders (Maker side) are completely free. This alone leaves a lot of room for strategy optimization.

Opinion's fee range is between 0% and 2%, but this rate is not fixed—it adjusts dynamically based on event probabilities. When the event probability approaches 0% or 100% (i.e., high certainty), the fee drops to the minimum or even near zero. Conversely, when the probability hovers around 50%, the fee reaches its maximum. This mechanism design is quite interesting, as it encourages participants to trade in high-certainty opportunities.

However, fees are just one dimension affecting returns. The real determinant of the final outcome is each individual's trading strategy. Some can earn significant profits with just a few thousand dollars in a week, while others invest tens of thousands of dollars with little gain—key lies in strategy choice. Some focus on quick points, some emphasize capital utilization efficiency, and others prioritize risk margins. These different tendencies are directly reflected in the data performance.

Account structure, operation volume, interaction frequency—all these factors can create chain reactions. Therefore, different players will have completely different costs and profit performances, which is normal.

Finally, I recommend a practical tool—you can use it to record address interaction counts and trading volume data, making it easier to verify if activity targets are met and to improve operational accuracy.
