Long synthetic forward
A systematic options approach—Long synthetic forward—defined by explicit rules, testable on history, and fragile when costs or regimes change.
Overview
This strategy amounts to buying an ATM call option and selling an ATM put option with a strike price K =S0. This can be a net debit or net credit trade.
Long synthetic forward sits in the Options chapter of the systematic catalog. On QUSXFI we treat it as a testable hypothesis: specify entries, exits, sizing, and costs—then ask whether edge survives out-of-sample scrutiny.
Discretionary traders often arrive at similar ideas intuitively; the quantitative version forces you to write the rule before you see the next bar. That discipline is what makes results reproducible—or exposes them as luck.
Based on the research catalog 151 Trading Strategies (Kakushadze & Serur, 2018), section 2.10. Educational summary—not a replication of the full formal definition.
How the Strategy Works
Long synthetic forward in Options is defined by explicit positions and transition rules—translate each clause into code or a checklist. The catalog frames it this way: This strategy amounts to buying an ATM call option and selling an ATM put option with a strike price K =S0. Your implementation must preserve that economic intent while making every parameter explicit.
The published definition of Long synthetic forward (catalog §2.10) specifies when exposure changes; discretionary overrides invalidate systematic claims.
Implementation and Research Process
Decompose Long synthetic forward into signal, portfolio construction, and execution modules—each must be path-independent given the same historical tape.
Stress Long synthetic forward costs at 2× baseline; many Options edges live or die on slippage alone.
Anchor Long synthetic forward research to the catalog definition, then stress every assumption the textbook silently skips. This strategy amounts to buying an ATM call option and selling an ATM put option with a strike price K =S0.
Risk: What Breaks This Strategy
Synthetic structures in Long synthetic forward rely on put-call parity and margin treatment that brokers do not always mirror in backtests.
Dividends, borrow, and early exercise on American options break clean synthetic relationships.
One leg fails to fill and you are directionally exposed without the offset you modeled.
