# Quick Start

Welcome to AKQuant! Let's run the simplest strategy as quickly as possible.

## 1. Installation

Open your terminal and run:

```bash
pip install akquant
```

## 2. Minimal Example

This strategy is very simple:

1. When Close > Open (Bullish) -> Buy
2. When Close < Open (Bearish) -> Sell

```python
import akshare as ak
from akquant import Strategy, run_backtest

# 1. Prepare Data (Using AKShare to get data, install via `pip install akshare`)
df = ak.stock_zh_a_daily(symbol="sh600000", start_date="20250101", end_date="20260212")


# 2. Define Strategy
class MyStrategy(Strategy):

    # 3. Strategy Logic
    def on_bar(self, bar):
        # Get current position
        current_pos = self.get_position(bar.symbol)
        # 1. When Close > Open (Bullish) -> Buy
        if current_pos == 0 and bar.close > bar.open:
            self.buy(bar.symbol, 100)  # Buy 100 shares

        # 2. When Close < Open (Bearish) -> Sell
        elif current_pos > 0 and bar.close < bar.open:
            self.close_position(bar.symbol)  # Sell all shares


# 3. Run Backtest
print("Starting backtest...")
result = run_backtest(
    data=df,  # Input data
    strategy=MyStrategy,  # Input strategy
    initial_cash=100000.0,  # Initial cash
    symbol="sh600000"  # Trading symbol
)

# 4. View Results
print(result)  # Equivalent to print(result.metrics_df)
```

In the output, you will see the complete performance metrics of the strategy:

## Report & Analysis Outputs

After the backtest, you can generate an interactive report directly:

```python
result.report(
    show=True,
    filename="report.html",
    compact_currency=True,
)

result.report(
    show=False,
    filename="report_raw_amount.html",
    compact_currency=False,
)
```

You can also reuse structured analysis outputs for downstream research:

```python
exposure = result.exposure_df()
attr_by_symbol = result.attribution_df(by="symbol")
attr_by_tag = result.attribution_df(by="tag")
capacity = result.capacity_df()
orders_by_strategy = result.orders_by_strategy()
executions_by_strategy = result.executions_by_strategy()
```

## Complex Orders in 30 Seconds

If you need an entry + stop-loss + take-profit flow with automatic OCO linkage, use `place_bracket_order` directly:

```python
from akquant import OrderStatus, Strategy

class BracketQuickStrategy(Strategy):
    def __init__(self):
        self.entry_order_id = ""

    def on_bar(self, bar):
        if self.get_position(bar.symbol) > 0 or self.entry_order_id:
            return
        self.entry_order_id = self.place_bracket_order(
            symbol=bar.symbol,
            quantity=100,
            stop_trigger_price=bar.close * 0.98,
            take_profit_price=bar.close * 1.04,
            entry_tag="entry",
            stop_tag="stop",
            take_profit_tag="take",
        )

    def on_order(self, order):
        if order.id == self.entry_order_id and order.status in (
            OrderStatus.Cancelled,
            OrderStatus.Rejected,
        ):
            self.entry_order_id = ""
```

## 3. Streaming Backtest

If you want real-time events during a backtest (progress, equity, orders, trades,
and final status), use `run_backtest` with `on_event`.

```python
from akquant import run_backtest

def on_event(event):
    if event["event_type"] == "finished":
        payload = event["payload"]
        print("status:", payload.get("status"))
        print("callback_error_count:", payload.get("callback_error_count"))

result = run_backtest(
    data=df,
    strategy=MyStrategy,
    symbol="sh600000",
    on_event=on_event,
    show_progress=False,
    stream_progress_interval=10,
    stream_equity_interval=10,
    stream_batch_size=32,
    stream_max_buffer=256,
    stream_error_mode="continue",
)
```

Common streaming options:

*   `stream_progress_interval`: sampling interval for `progress` events (positive int)
*   `stream_equity_interval`: sampling interval for `equity` events (positive int)
*   `stream_batch_size`: flush threshold for buffered events (positive int)
*   `stream_max_buffer`: maximum buffered event count (positive int)
*   `stream_error_mode`: callback exception policy
    *   `"continue"`: continue backtest on callback exceptions and report summary in
        `finished.payload`
    *   `"fail_fast"`: stop immediately and raise an exception on callback errors

Stream event common fields:

*   `run_id`: stream run id
*   `seq`: monotonic event sequence
*   `ts`: event timestamp in nanoseconds
*   `event_type`: event type
*   `symbol`: related symbol (nullable for some events)
*   `level`: event level
*   `payload`: event payload

Phase-5 Migration FAQ:

*   Is `run_backtest` renamed? No, the public entry name stays unchanged.
*   Can `run_backtest` still be called without `on_event`? Yes, and result-return semantics stay the same.
*   How do we roll back? Since Phase 5, `_engine_mode` runtime fallback is removed; use release-level rollback.
*   Home navigation entry: see [Quick Links in docs home](../index.md#quick-links).
