        max_position_size: 100.0,
        spread_bps: 50, // 0.5% spread
        verbose: true,
    };

    // Create strategy
    let market_id = "market-condition-id".to_string();
    let mut strategy = BaseStrategy::new(
        exchange.clone(),
        market_id,
        strategy_config
    );

    // Run strategy loop
    strategy.run_loop(|strat| async move {
        // Get current state
        let account = strat.get_account_state().await?;
        let net_position = strat.get_net_position();

        strat.log(&format!("Net position: {:.2}", net_position));

        // Calculate order prices
        let mid_price = 0.50; // Get from orderbook
        let (bid, ask) = strat.calculate_spread_prices(mid_price, 50);
        let size = strat.calculate_order_size(mid_price, 1000.0);

        // Place orders if within risk limits
        if net_position.abs() < 100.0 {
            // Cancel old orders
            strat.cancel_all_orders().await?;

            // Place new orders
            if let Some(market) = &strat.market {
                let outcome = &market.outcomes[0];
                strat.place_order(outcome, OrderSide::Buy, bid, size, None).await?;
                strat.place_order(outcome, OrderSide::Sell, ask, size, None).await?;

Source: https://context7.com/gtg7784/dr-manhattan-rust/llms.txt

Retrieves all currently open orders for the authenticated account on the Limitless exchange. It iterates through the orders and prints details such as ID, market, outcome, side, price, size, and fill percentage. Requires Limitless API credentials.

```rust
use drm_core::Exchange;
use drm_exchange_limitless::{Limitless, LimitlessConfig};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let config = LimitlessConfig::new()
        .with_private_key("0xYOUR_PRIVATE_KEY");
    let exchange = Limitless::new(config)?;
    exchange.authenticate().await?;

    let orders = exchange.fetch_open_orders(None).await?;

    for order in orders {
        println!("Order ID: {}", order.id);
        println!("Market: {}", order.market_id);
        println!("Outcome: {} | Side: {:?}", order.outcome, order.side);
        println!("Price: ${:.4} | Size: {:.2}", order.price, order.size);
        println!("Filled: {:.1}%", order.fill_percentage() * 100.0);
        println!("Is Active: {}", order.is_active());

### Exchange Trait Methods

Source: https://github.com/gtg7784/dr-manhattan-rust/blob/main/README.md

This section details the methods available within the `Exchange` trait for interacting with prediction exchanges.

```APIDOC
## Exchange Trait

All exchanges implement the `Exchange` trait, providing a unified interface for interacting with prediction markets.

### Methods

- **`id()`**: Returns the unique identifier of the exchange.
- **`name()`**: Returns the human-readable name of the exchange.
- **`fetch_markets(params: Option<FetchMarketsParams>)`**: Fetches a list of all available markets on the exchange.
- **`fetch_market(market_id: &str)`**: Fetches a specific market by its ID.
- **`fetch_markets_by_slug(slug: &str)`**: Fetches markets associated with a given slug.
- **`create_order(...)`**: Creates a new order on the exchange.
- **`cancel_order(order_id: &str, market_id: Option<&str>)`**: Cancels an existing order.
- **`fetch_order(order_id: &str, market_id: Option<&str>)`**: Fetches details of a specific order.
- **`fetch_open_orders(params: Option<FetchOrdersParams>)`**: Fetches a list of all open orders.
- **`fetch_positions(market_id: Option<&str>)`**: Fetches current positions held by the user.
- **`fetch_balance()`**: Fetches the user's account balance.

### Models

- **`Market`**: Represents a prediction market, including question, outcomes, prices, and volume.
- **`Order`**: Represents an order, containing details like price, size, status, and timestamps.
- **`Position`**: Represents a user's position in a market, including size, average entry price, and current price.
- **`Orderbook`**: Represents the order book for a market, detailing bids and asks.
```

### Fetch Price History in Rust

Source: https://context7.com/gtg7784/dr-manhattan-rust/llms.txt

Fetches historical price data for a specific market outcome over a defined time interval. This is useful for analyzing market trends and past performance. It requires a market ID, an optional outcome index, an interval (e.g., hourly), and a lookback period.

```rust
use drm_core::PriceHistoryInterval;
use drm_exchange_polymarket::{Polymarket, PolymarketConfig};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let exchange = Polymarket::with_default_config()?;

    let market_id = "market-condition-id";
    let outcome_index = 0; // First outcome

    // Fetch price history
    let history = exchange.fetch_price_history(
        market_id,
        Some(outcome_index),
        PriceHistoryInterval::OneHour,
        Some(24) // Last 24 hours
    ).await?;

    println!("Price history ({} points):", history.len());
    for point in history {
        println!("{}: ${:.4}",
            point.timestamp.format("%Y-%m-%d %H:%M"),
            point.price);
    }

    Ok(())
}
```

### Rust: WebSocket Orderbook Streaming from Polymarket

Source: https://github.com/gtg7784/dr-manhattan-rust/blob/main/drm-exchange-polymarket/README.md

Shows how to subscribe to real-time order book updates from the Polymarket exchange using WebSockets in Rust. It connects to the WebSocket, subscribes to a specific token ID's order book, and prints incoming bid and ask data.

```rust
use drm_exchange_polymarket::PolymarketWebSocket;
use drm_core::WebSocketClient;

let ws = PolymarketWebSocket::new();
let mut stream = ws.subscribe_orderbook("token_id").await?;

while let Some(orderbook) = stream.next().await {
    println!("Bids: {{:?}}, Asks: {{:?}}", orderbook.bids, orderbook.asks);
}

```

--------------------------------

### Subscribe to WebSocket Orderbook Stream in Rust

Source: https://context7.com/gtg7784/dr-manhattan-rust/llms.txt

Connects to a WebSocket, subscribes to a specific token, and processes real-time orderbook updates. It prints market ID, best bid/ask, mid-price, spread, and the number of bid/ask levels. Dependencies include `drm_core`, `drm_exchange_polymarket`, and `futures`. Inputs are a token ID, and outputs are printed to the console. Limitations may include network connectivity and token validity.

```rust
use drm_core::OrderBookWebSocket;
use drm_exchange_polymarket::PolymarketWebSocket;
use futures::StreamExt;

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let mut ws = PolymarketWebSocket::new();

    // Connect to WebSocket
    ws.connect().await?;
    println!("Connected to WebSocket");

    // Subscribe to a specific token
    let token_id = "21742633143463906290569050155826241533067272736897614950488156847949938836455";
    ws.subscribe(token_id).await?;
    println!("Subscribed to token: {}", token_id);

    // Get orderbook stream
    let mut stream = ws.orderbook_stream(token_id).await?;

    // Process orderbook updates
    while let Some(result) = stream.next().await {
        let orderbook = result?;

        println!("Market: {}", orderbook.market_id);

        // Get best bid and ask
        if let (Some(bid), Some(ask)) = (orderbook.best_bid(), orderbook.best_ask()) {
            let mid = orderbook.mid_price().unwrap_or(0.0);
            let spread = orderbook.spread().unwrap_or(0.0);

            println!("Best Bid: {:.4} | Best Ask: {:.4}", bid, ask);
            println!("Mid Price: {:.4} | Spread: {:.4}", mid, spread);
        }

        // Access price levels
        println!("Bids: {} levels | Asks: {} levels",
            orderbook.bids.len(),
            orderbook.asks.len());

        for level in orderbook.bids.iter().take(5) {
            println!("  Bid: {:.4} @ {:.0}", level.price, level.size);
        }
    }

    ws.disconnect().await?;
    Ok(())
}

### Fetch Markets by Slug - Polymarket (Rust)

Source: https://context7.com/gtg7784/dr-manhattan-rust/llms.txt

Searches for prediction markets on Polymarket associated with a specific event slug or URL. This function demonstrates retrieving markets by slug and accessing their questions and token IDs, including mapping outcomes to token IDs. Requires the `drm-core` and `drm-exchange-polymarket` crates.

```rust
use drm_core::Exchange;
use drm_exchange_polymarket::{Polymarket, PolymarketConfig};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let exchange = Polymarket::with_default_config()?;

    // Can use either slug or full URL
    let slug = "presidential-election-2024";
    // Or: let slug = "https://polymarket.com/event/presidential-election-2024";

    let markets = exchange.fetch_markets_by_slug(slug).await?;

    for market in markets {
        println!("Market: {}", market.question);
        println!("Token IDs: {:?}", market.get_token_ids());

        // Get outcome-token pairs
        for outcome_token in market.get_outcome_tokens() {
            println!("{}: {}", outcome_token.outcome, outcome_token.token_id);
        }
    }

    Ok(())
}
```

### Rust: Define Exchange Trait for Prediction Market Operations

Source: https://github.com/gtg7784/dr-manhattan-rust/blob/main/drm-core/README.md

This Rust code defines the `Exchange` trait, which serves as a unified asynchronous interface for all prediction market operations. It includes methods for fetching markets, fetching a specific market, and creating orders. This trait is designed to be implemented by concrete exchange integrations.

```rust
use drm_core::{Exchange, Market, Order, OrderSide, DrmError};

// The Exchange trait defines the unified API
#[async_trait]
pub trait Exchange: Send + Sync {
    fn id(&self) -> &'static str;
    fn name(&self) -> &'static str;
    
    async fn fetch_markets(&self, params: Option<FetchMarketsParams>) -> Result<Vec<Market>, DrmError>;
    async fn fetch_market(&self, market_id: &str) -> Result<Market, DrmError>;
    async fn create_order(&self, ...) -> Result<Order, DrmError>;
    // ... more methods
}

```

--------------------------------

### Rust Exchange Trait Definition

Source: https://github.com/gtg7784/dr-manhattan-rust/blob/main/README.md

Defines the `Exchange` trait in Rust, which all exchange implementations must adhere to. This trait specifies asynchronous methods for fetching market and order data, creating and canceling orders, and managing positions and balances. It requires implementations to be thread-safe (`Send + Sync`).

```rust
pub trait Exchange: Send + Sync {
    fn id(&self) -> &'static str;
    fn name(&self) -> &'static str;
    
    async fn fetch_markets(&self, params: Option<FetchMarketsParams>) -> Result<Vec<Market>, DrmError>;
    async fn fetch_market(&self, market_id: &str) -> Result<Market, DrmError>;
    async fn fetch_markets_by_slug(&self, slug: &str) -> Result<Vec<Market>, DrmError>;
    
    async fn create_order(&self, market_id: &str, outcome: &str, side: OrderSide, price: f64, size: f64, params: HashMap<String, String>) -> Result<Order, DrmError>;
    async fn cancel_order(&self, order_id: &str, market_id: Option<&str>) -> Result<Order, DrmError>;
    async fn fetch_order(&self, order_id: &str, market_id: Option<&str>) -> Result<Order, DrmError>;
    async fn fetch_open_orders(&self, params: Option<FetchOrdersParams>) -> Result<Vec<Order>, DrmError>;
    
    async fn fetch_positions(&self, market_id: Option<&str>) -> Result<Vec<Position>, DrmError>;
    async fn fetch_balance(&self) -> Result<HashMap<String, f64>, DrmError>;
}
```

### Fetch Positions on Polymarket (Rust)

Source: https://context7.com/gtg7784/dr-manhattan-rust/llms.txt

Queries current positions held in a specific market or across all markets on Polymarket. It displays details for each position including outcome, size, average price, current price, cost basis, current value, and P&L. Requires Polymarket API credentials.

```rust
use drm_core::Exchange;
use drm_exchange_polymarket::{Polymarket, PolymarketConfig};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let config = PolymarketConfig::new()
        .with_private_key("0xYOUR_PRIVATE_KEY");
    let exchange = Polymarket::new(config)?;
    exchange.init_trading().await?;

    // Fetch positions for specific market
    let market_id = "market-condition-id";
    let positions = exchange.fetch_positions(Some(market_id)).await?;

    for position in positions {
        println!("Outcome: {}", position.outcome);
        println!("Size: {:.2} shares", position.size);
        println!("Avg Price: ${:.4}", position.average_price);
        println!("Current Price: ${:.4}", position.current_price);
        println!("Cost Basis: ${:.2}", position.cost_basis());
        println!("Current Value: ${:.2}", position.current_value());
        println!("Unrealized P&L: ${:.2} ({:.1}%)",
            position.unrealized_pnl(),
            position.unrealized_pnl_percent());
        println!("---
");
    }

    Ok(())
}
```

### Cancel Order on Polymarket (Rust)

Source: https://context7.com/gtg7784/dr-manhattan-rust/llms.txt

Cancels an existing open order on Polymarket using its unique order ID. The market ID can optionally be provided. Requires Polymarket API credentials.

```rust
use drm_core::Exchange;
use drm_exchange_polymarket::{Polymarket, PolymarketConfig};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let config = PolymarketConfig::new()
        .with_private_key("0xYOUR_PRIVATE_KEY");
    let exchange = Polymarket::new(config)?;
    exchange.init_trading().await?;

    let order_id = "order-id-to-cancel";
    let market_id = Some("market-id"); // Optional for some exchanges

    let cancelled_order = exchange.cancel_order(order_id, market_id).await?;

    println!("Cancelled order: {}", cancelled_order.id);
    println!("Status: {:?}", cancelled_order.status);

    Ok(())
}
