From a24c0b9aa39fac8c175c94ca950beaf8e03d761f Mon Sep 17 00:00:00 2001 From: Joaquin Bejar Date: Thu, 16 Apr 2026 17:47:16 +0200 Subject: [PATCH 01/10] feat(error): add NumericConversion, MissingGreek, EmptyCollection variants MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Extend StrategyError with three typed variants needed by the strategies/ panic-free refactor (issue #316): - NumericConversion { value: f64 } for failed f64 → Decimal conversions at the numeric kernel boundary. - MissingGreek { name: &'static str } for options that lack a greek the caller requires (delta-neutral validators, etc.). - EmptyCollection { context: String } for unexpectedly empty option chains, break-even point sets, or profit ranges. Add #[cold] #[inline(never)] constructors. Wire ProbabilityError::From arms for the three new variants so the existing conversion stays total. --- src/error/probability.rs | 9 +++++ src/error/strategies.rs | 71 ++++++++++++++++++++++++++++++++++++++++ 2 files changed, 80 insertions(+) diff --git a/src/error/probability.rs b/src/error/probability.rs index f3d4a165..22ce1fd0 100644 --- a/src/error/probability.rs +++ b/src/error/probability.rs @@ -462,6 +462,15 @@ impl From for ProbabilityError { } StrategyError::GreeksError(err) => ProbabilityError::StdError(err.to_string()), StrategyError::PositiveError(err) => ProbabilityError::StdError(err.to_string()), + StrategyError::NumericConversion { value } => ProbabilityError::StdError(format!( + "numeric conversion failed: {value} is not a finite Decimal" + )), + StrategyError::MissingGreek { name } => { + ProbabilityError::StdError(format!("missing greek `{name}`")) + } + StrategyError::EmptyCollection { context } => { + ProbabilityError::StdError(format!("empty collection: {context}")) + } } } } diff --git a/src/error/strategies.rs b/src/error/strategies.rs index e5e88d35..7a4f011a 100644 --- a/src/error/strategies.rs +++ b/src/error/strategies.rs @@ -128,6 +128,38 @@ pub enum StrategyError { /// Positive value errors #[error(transparent)] PositiveError(#[from] positive::PositiveError), + + /// Numeric conversion failed at the `f64` ↔ `Decimal` boundary. + /// + /// Raised when a non-finite (`NaN` / `±Inf`) `f64` cannot be represented + /// as a `Decimal`, or when a representation overflow occurs. + #[error("numeric conversion failed: {value} is not a finite Decimal")] + NumericConversion { + /// The offending `f64` value that could not be converted. + value: f64, + }, + + /// A required greek value was missing from an option. + /// + /// Raised when a strategy expects a greek (delta, gamma, vega, theta, + /// rho) to be present on an option (e.g., for delta-neutral validation) + /// but the option's greek calculation returned `None`. + #[error("missing greek `{name}`: option not initialized for greek calculation")] + MissingGreek { + /// Name of the greek (`"delta"`, `"gamma"`, `"vega"`, `"theta"`, `"rho"`). + name: &'static str, + }, + + /// A required collection was empty when at least one element was expected. + /// + /// Raised when a strategy operation needs to pick an element out of a + /// collection (option chain, break-even points, profit ranges) and the + /// collection turned out to be empty. + #[error("empty collection in strategy operation: {context}")] + EmptyCollection { + /// Description of where the empty collection was encountered. + context: String, + }, } /// Represents different types of errors that can occur during price-related operations. @@ -338,6 +370,45 @@ impl StrategyError { reason: reason.to_string(), }) } + + /// Builds a `NumericConversion` error for an `f64` that could not be + /// converted to a `Decimal` (typically `NaN` / `Inf` or overflow). + /// + /// # Errors + /// + /// This is an error constructor — it always returns the variant. + #[cold] + #[inline(never)] + #[must_use] + pub fn numeric_conversion(value: f64) -> Self { + StrategyError::NumericConversion { value } + } + + /// Builds a `MissingGreek` error for an option missing a required greek. + /// + /// # Errors + /// + /// This is an error constructor — it always returns the variant. + #[cold] + #[inline(never)] + #[must_use] + pub fn missing_greek(name: &'static str) -> Self { + StrategyError::MissingGreek { name } + } + + /// Builds an `EmptyCollection` error for an unexpectedly empty collection. + /// + /// # Errors + /// + /// This is an error constructor — it always returns the variant. + #[cold] + #[inline(never)] + #[must_use] + pub fn empty_collection(context: impl Into) -> Self { + StrategyError::EmptyCollection { + context: context.into(), + } + } } impl From for StrategyError { From 2a0346328bf2a2a31f69d8c9134bc9ee9fab6b0a Mon Sep 17 00:00:00 2001 From: Joaquin Bejar Date: Thu, 16 Apr 2026 18:00:16 +0200 Subject: [PATCH 02/10] refactor(strategies): make Optimizable::create_strategy fallible MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Tighten the `Optimizable::create_strategy` trait signature in src/strategies/base.rs from `-> Self::Strategy` to `-> Result`. The default impl now returns `OperationError(NotSupported)` instead of `unimplemented!()`. Update all 14 concrete impls (bear/bull call/put spreads, iron condor/ butterfly, call/long/short butterfly, long/short strangle, long/short straddle, poor_mans_covered_call) to: - Wrap the constructed strategy in `Ok(...)`. - Replace `.unwrap()` on `OptionData::call_bid` / `call_ask` / `put_bid` / `put_ask` with `.ok_or_else(...)?` mapped to `StrategyError::operation_not_supported(..., "missing ...")`. - Replace `.expect("Invalid position")` on builder helpers (`add_position`, `update_break_even_points`) with `?`. - Add a `# Errors` section to the doc comment. Update all ~40 callers: - Inside `filter_combinations` filter closures: convert `let strategy = ...; strategy.validate() && ...` to a `match` returning `false` on `Err(_)`. - Inside `find_optimal` for-loops: extract the strategy via `match` with `tracing::warn!(error = %e, "skipping invalid strategy combination"); continue;` on `Err`. - Test callers (`#[cfg(test)]`) propagate via `.unwrap()` / `.expect(...)` per project rules (out of scope of issue #316 grep). - The two intentionally-bad-leg tests (`call_butterfly`, `iron_butterfly`, `iron_condor`) now assert `.is_err()` rather than catching a panic. Existing `panic!` / `unreachable!` / `unimplemented!` are intentionally left in place — they belong to issue #292. `cargo build --all-targets --all-features` clean. `cargo test --lib strategies::` 1202 passed. Eliminates ~40 of the 236 production `.unwrap()/.expect()` sites under src/strategies/ (236 → 196).

Highlights: - base.rs::is_valid_optimal_option (DeltaRange arm) rewritten with is_some_and so it can no longer panic on missing greeks. - base.rs sort comparators use unwrap_or(Ordering::Equal) with a SAFETY comment; Decimal/Positive are total-ordered, f64 fallback is stable. - base.rs::get_total_cost / get_net_cost / get_net_premium_received switched to ?-propagation via for-loops (signatures unchanged). - short_strangle.rs and long_strangle.rs delta-neutral filter closures bind greeks once and short-circuit to false on None. - find_optimal loops in both strangles match the new fallible create_strategy and continue with tracing::warn! on Err. - get_profit_area / get_profit_ratio map Decimal::from_f64 NaN/Inf to StrategyError::numeric_conversion(...). API change (intentional, M1 panic-free milestone): - ShortStrangle::new(...) and LongStrangle::new(...) now return Result (was Self). The constructors used to .expect(...) on their own builder helpers; that pattern is replaced with ? propagation. All in-tree callers (tests, examples, dependent strategies) updated. Build: cargo build --all-targets --all-features clean. Tests: cargo test --lib strategies:: 1202 passed; 0 failed. Production unwrap/expect under src/strategies/: 196 -> 138 (58 eliminated this commit).

Highlights: - iron_condor / iron_butterfly: sort comparators in get_strategy use unwrap_or(Ordering::Equal); find_optimal loops match/continue with tracing::warn! on unscorable metrics; Decimal::from_f64 in get_profit_area maps to StrategyError::numeric_conversion(...); fee_per_leg bound once via ? in create_strategy. - custom.rs::refine_break_even_point() rewritten so calculate_profit_at short-circuits via .ok()? instead of panicking; eliminated a latent duplicated f_x recompute. - custom.rs::calculate_pnl / calculate_pnl_at_expiration rewritten as for-loop with ?; probability for_each(...).unwrap() blocks turned into for ... { ... ? } chains. API changes (intentional, M1 panic-free milestone): - IronCondor::new(...) now returns Result (was Self). Drops three .expect("Invalid ") and one .expect("Unable to update break even points"). - IronButterfly::new(...) same change, same rationale. - CustomStrategy::new(...) now returns Result (was Self). Drops .expect("Unable to update break even points"). The panic!("Invalid strategy: No positions provided") invariant remains (issue #292) and is documented in # Panics.

Highlights: - Sort comparators in get_strategy paths use unwrap_or(Ordering::Equal). - find_optimal loops match/continue with tracing::warn! on unscorable metrics. - Decimal::from_f64 in get_profit_area / get_profit_ratio maps to StrategyError::numeric_conversion(...). - call_butterfly::get_profit_ratio chains self.get_max_loss() via ?. API changes (intentional, M1 panic-free milestone): - CallButterfly::new(...), PoorMansCoveredCall::new(...), ShortStraddle::new(...), and LongStraddle::new(...) now return Result (were Self). Drops .expect("Invalid ") and .expect("Unable to update break even points") from each constructor body. All in-tree call sites (tests, examples, dependent strategies, benches) updated. Build: cargo build --all-targets --all-features clean. Tests: cargo test --lib strategies:: 1202 passed; 0 failed. Production unwrap/expect under src/strategies/: 103 -> 71 (32 eliminated this commit).

Highlights: - Sort comparators in every spread's get_strategy path use unwrap_or(Ordering::Equal) with a SAFETY comment. - find_optimal loops match/continue with tracing::warn! on unscorable metrics. - graph.rs: range.first()/last().unwrap() rewritten as if-let guard; calculate_profit_at(&price).unwrap() in the per-price loop matches and continues with tracing::warn! on Err; current_sign.unwrap() bindings folded into match/let-else patterns. API changes (intentional, M1 panic-free milestone): - BullCallSpread::new(...), BearCallSpread::new(...), BullPutSpread::new(...), BearPutSpread::new(...), LongButterflySpread::new(...), and ShortButterflySpread::new(...) now return Result (were Self). Drops .expect("Invalid ") and .expect("Unable to update break even points") from each constructor body. All in-tree call sites (tests, examples, dependent strategies, benches) updated. Build: cargo build --all-targets --all-features clean. Tests: cargo test --lib strategies:: 1202 passed; 0 failed. Production unwrap/expect under src/strategies/: 71 -> 27 (44 eliminated this commit).

charset=UTF-8 Content-Transfer-Encoding: 8bit Eliminate the final 27 production .unwrap() / .expect() under src/strategies/. Total panic-free count for the milestone: 0. Highlights: - probabilities/core.rs: HashMap .values().next().unwrap() → StrategyError::empty_collection(...); get_break_even_points / get_best_range / get_profit_ratio chained via ?. Decimal::to_f64() in expected_value rewritten as a for-loop with NumericConversion fallback. - probabilities/utils.rs: risk_free.to_f64() bound once per arm with ?-propagation into ProbabilityError::StdError; f2du! and big_n() unwraps replaced by ? (existing #[from] DecimalError chain). - delta_neutral/optimizer.rs: best_plan.as_ref().unwrap() rewritten with is_none_or; partial_cmp(...).unwrap() sort comparators → unwrap_or(Ordering::Equal) with SAFETY comment. - delta_neutral/model.rs: per-leg option.delta().unwrap() folded into a for-loop with ? and bound once (was duplicated greek call). - Single-leg / spot-paired strategies (long/short_call, long/short_put, protective_put, covered_call, collar): add_position(...).expect(...) → ?; Positive::new(0.001).unwrap() in simulator path → ?; ProgressStyle::default_bar().template(...).expect(...) → map_err to SimulationError::OtherError. - Doctests in probabilities/mod.rs rewrapped with `# fn run() -> Result<(), Box>` to keep ? working after the constructor / analyze_probabilities API tightening. API changes (intentional, M1 panic-free milestone): - LongCall::new(...), LongPut::new(...) (private), ShortCall::new(...) (private), ShortPut::new(...), ProtectivePut::new(...), CoveredCall::new(...), and Collar::new(...) now return Result (were Self). The trio of single-name spot-paired constructors (protective_put / covered_call / collar) also drop their #[must_use] (Result already carries it). All workspace callers (tests, examples, benches) updated. Build: cargo build --all-targets --all-features clean. Tests: cargo test --lib strategies:: 1202 passed; 0 failed. Doctests: probabilities 6 passed. ACCEPTANCE GREP — production unwrap/expect under src/strategies/: 0.
