That's a great point! Encouraging counter-trading is a key mechanism for AMMs to balance the order book. By adjusting prices, AMMs create incentives for traders to take the opposite side of the trade, which helps to:

1. Reduce imbalances: By encouraging counter-trading, AMMs reduce the imbalance between buy and sell orders.

2. Increase liquidity: Counter-trading adds liquidity to the market, making it easier for traders to buy and sell.

3. Improve price discovery: Counter-trading helps to reveal true market prices, as traders are incentivized to take the opposite side of the trade.

4. Enhance market efficiency: By encouraging counter-trading, AMMs promote market efficiency, as prices better reflect genuine market sentiment.

5. Reduce volatility: Counter-trading can help reduce price fluctuations, as opposing trades help to stabilize the market.

AMMs encourage counter-trading by:

1. Adjusting prices to make the opposite side of the trade more attractive.

2. Providing liquidity incentives for counter-traders.

3. Using algorithms that detect and respond to order book imbalances.

By encouraging counter-trading, AMMs create a more balanced and efficient market, benefiting traders and the overall market ecosystem.
