# paracas-lib
|
|
|
|
High-performance Rust library for downloading historical tick data from Dukascopy.
|
|
|
|
## Features
|
|
|
|
- **Fast**: Concurrent downloads with connection pooling
|
|
- **Flexible**: CSV, JSON, and Parquet output formats
|
|
- **Complete**: All 1000+ Dukascopy instruments supported
|
|
- **Aggregation**: Built-in OHLCV aggregation
|
|
|
|
## Quick Start
|
|
|
|
```rust,ignore
|
|
use paracas_lib::prelude::*;
|
|
use futures::StreamExt;
|
|
|
|
#[tokio::main]
|
|
async fn main() -> Result<(), Box<dyn std::error::Error>> {
|
|
// Get instrument
|
|
let registry = InstrumentRegistry::global();
|
|
let instrument = registry.get("eurusd").unwrap();
|
|
|
|
// Create client
|
|
let client = DownloadClient::with_defaults()?;
|
|
|
|
// Define date range
|
|
let range = DateRange::new(
|
|
chrono::NaiveDate::from_ymd_opt(2024, 1, 1).unwrap(),
|
|
chrono::NaiveDate::from_ymd_opt(2024, 1, 1).unwrap(),
|
|
)?;
|
|
|
|
// Stream ticks
|
|
let mut stream = tick_stream(&client, instrument, range);
|
|
while let Some(batch) = stream.next().await {
|
|
let batch = batch?;
|
|
println!("Downloaded {} ticks for {:?}", batch.len(), batch.hour);
|
|
}
|
|
|
|
Ok(())
|
|
}
|
|
```
|
