Module main

Support & Resistance Module

This module implements a support/resistance indicator based on swing highs and lows. It keeps a sliding window of prices (with a customizable period) and calculates support and resistance levels using a specified threshold (default is 2%).

The module provides a calculate method that returns an SRResult containing:

• The nearest support level
• The nearest resistance level
• A support strength (0-100%)
• A resistance strength (0-100%)
• A breakout potential (based on the weaker of the two strengths)
• A price position (relative to the support/resistance levels)

Example

use indexes_rs::v1::support_resistance::main::SupportResistance;
use indexes_rs::v1::support_resistance::types::{SRResult, PricePosition};

let mut sr = SupportResistance::new(SupportResistance::DEFAULT_PERIOD, SupportResistance::DEFAULT_THRESHOLD);

// Simulate adding prices (in a real scenario, these would be updated on every tick)
let prices = vec![100.0, 101.0, 102.0, 101.5, 100.5, 99.0, 98.5, 99.5, 100.0, 101.0, 102.0, 103.0];
let mut result: Option<SRResult> = None;
for price in prices {
    result = sr.calculate(price);
}

if let Some(res) = result {
    println!("Nearest support: {:?}", res.nearest_support);
    println!("Nearest resistance: {:?}", res.nearest_resistance);
    println!("Support strength: {:.2}%", res.support_strength);
    println!("Resistance strength: {:.2}%", res.resistance_strength);
    println!("Breakout potential: {:.2}%", res.breakout_potential);
    println!("Price position: {:?}", res.price_position);
}
