Load when: comparing prices, rounding to tick size, formatting for display/broker APIs, parsing market feeds, designing price types or SymbolSpec structs.\"\nlicense: MIT\nuser-invocable: true\nmetadata:\n  author: vanillagreen\n  source: kendex\n  repository: \"https://github.com/vanillagreencom/kendex\"\n  bugs: \"https://github.com/vanillagreencom/kendex/issues\"\n  version: \"1.0.0\"\ntags: [data]\n---\n\n# Price Handling Patterns\n\n> **Problem with this skill?** Run `kendex report` — it files to the owning repo automatically. Do not hand-file.\n\n## The price type is `f64`\n\nIEEE 754 double precision. No fixed-point, no decimal types.\n\nUse `i64` fixed-point **only** for a matching engine (bit-exact required), a regulatory audit trail mandating reproducibility, or a settlement system with legal precision requirements. Hybrid: `i64` on the execution hot path, `f64` for display and analytics.\n\n## Never `==` on prices\n\n```rust\nuse float_cmp::{approx_eq, F64Margin};\n\npub const PRICE_EPSILON: f64 = 1e-10;  // sub-pipette tolerance\n\npub fn prices_equal(a: f64, b: f64) -> bool {\n    approx_eq!(f64, a, b, epsilon = PRICE_EPSILON, ulps = 4)\n}\n\npub fn price_gte(a: f64, b: f64) -> bool { a > b || prices_equal(a, b) }\npub fn price_lte(a: f64, b: f64) -> bool { a < b || prices_equal(a, b) }\n```\n\n## Round only at the boundaries\n\n| Boundary | Rounding |\n|---|---|\n| Order submission (OrderRequest → broker API) | Round to tick, then validate alignment |\n| Display formatting | Round to the symbol's `display_decimals` |\n| Market data ingestion (ticks, bars, quotes) | **Never** — preserve full feed precision |\n| P&L calculation | **Never** — use raw values |\n\n```rust\npub fn round_to_tick(price: f64, tick_size: f64) -> f64 {\n    (price / tick_size).round() * tick_size\n}\n\npub fn validate_tick_alignment(price: f64, tick_size: f64) -> bool {\n    prices_equal(price, round_to_tick(price, tick_size))\n}\n```\n\nOrder submission order: round to tick, validate alignment (on failure return an error — never re-round), then format for the broker API if it takes a string.\n\nFormat with the symbol's precision, never hardcoded decimals (EURUSD 5, AAPL 2, BTC 8):\n\n```rust\nformat!(\"{:.1$}\", price, symbol.display_decimals as usize)\n```\n\n## Symbol metadata owns precision\n\nTick size and display precision belong to the symbol, not to the price value. A `Price { value, decimals }` struct is the wrong shape.\n\n```rust\n#[derive(Clone, Copy)]\npub struct SymbolSpec {\n    pub symbol_id: u32,\n    pub tick_size: f64,         // minimum price increment\n    pub display_decimals: u8,   // decimal places for UI\n    pub lot_size: f64,          // minimum quantity\n}\n\nimpl SymbolSpec {\n    pub fn round_price(&self, price: f64) -> f64 {\n        round_to_tick(price, self.tick_size)\n    }\n\n    pub fn format_price(&self, price: f64) -> String {\n        format!(\"{:.1$}\", price, self.display_decimals as usize)\n    }\n}\n```\n\nThe symbol table loads at subscription setup (cold path), is keyed by symbol ID, and re-syncs on reconnect or symbol list change.\n\n## Price newtype\n\nOptional: wrap `f64` in a `#[repr(transparent)]` newtype with `PartialOrd` but **no `PartialEq`**; equality goes through `prices_equal`. Constructor `debug_assert!`s `is_finite()`. Use for order types; skip on the market-data hot path.\n\n## Normalize feeds to `f64` at ingest\n\nConvert at the entry boundary; downstream code sees plain `f64` regardless of feed source.\n\n```rust\n// doubles (IB, dxFeed, Rithmic): pass through\nfn ingest_double(value: f64) -> f64 { value }\n\n// strings (Binance, Coinbase): parse\nfn ingest_string(s: &str) -> Result<f64, ParseFloatError> { s.parse() }\n\n// scaled integers (CME MDP): unscale\nfn ingest_scaled(mantissa: i64, exponent: i8) -> f64 {\n    mantissa as f64 * 10f64.powi(exponent as i32)\n}\n```\n","tagline":"f64 price patterns for trading systems.
