Module condition 

Condition system for building strategy entry/exit rules.

This module provides a composable way to define trading conditions using indicator references and comparison operations.

Example

use finance_query::backtesting::refs::*;
use finance_query::backtesting::condition::*;

// Simple condition
let oversold = rsi(14).below(30.0);

// Compound conditions
let entry = rsi(14).crosses_below(30.0)
    .and(price().above_ref(sma(200)));

let exit = rsi(14).crosses_above(70.0)
    .or(stop_loss(0.05));
