Fetch historical data from MetaTrader 5.
|
|||
|
|
|
|||
|
|
- `symbol`: Trading instrument (e.g., "BTCUSD").
|
|||
|
|
- `n_bars`: Number of bars to retrieve.
|
|||
|
|
- `timeframe`: MT5 timeframe (e.g., mt5.TIMEFRAME_H1).
|
|||
|
|
- `start_pos`: Offset from the most recent bar (default `None` for live trading).
|
|||
|
|
|
|||
|
|
If `start_pos` is `None`, fetches the latest `n_bars` (useful for live trading).
|
|||
|
|
If `start_pos` is given, fetches `n_bars` from that historical position (useful for backtesting).
