pnf (Rust)

pnf is the official Rust binding for the PnF (Point and Figure) chart engine.

It exposes:

• Chart construction with P&F box/reversal rules.
• Indicator calculations (SMA, Bollinger, RSI, OBV, signals, patterns, support/resistance, congestion).
• JSON/ASCII exports.
• A real-time localhost dashboard server.

Installation

[dependencies]
pnf = "0.1.0"

Quick Start

use pnf::{Chart, Indicators};

fn main() {
    let mut chart = Chart::new();
    chart.add_price(5000.0, 1_700_000_000);
    chart.add_price(5030.0, 1_700_000_001);

    let mut indicators = Indicators::new();
    indicators.calculate(&chart);

    println!("{}", chart.to_ascii());
    println!("{}", indicators.summary());
}

Real-Time Dashboard

use pnf::DashboardServer;

let mut server = DashboardServer::new();
server.start("127.0.0.1", 8763).unwrap();
server.publish(&chart, &indicators).unwrap();
println!("{}", server.url());

Troubleshooting

• If docs.rs build fails, verify optional dependencies/features are docs-safe.
• Keep pnf crate version aligned with the same released core version.
• If linking errors occur in local workspace development, rebuild the core project first.
