Everyone quotes funding-arb returns; almost nobody walks through a single trade end to end. Here's one full cycle of a delta-neutral carry position — the sizing, the two entries, what every settlement actually pays, the mid-life basis wobble that scares people out, and the exit arithmetic.

Same Code, Everywhere: From on_bar() Backtest to Live Cron in One Engine

The deadliest gap in systematic trading is between the code you backtested and the code that trades live. We close it by running the exact same engine in both — preflight in milliseconds, backtest in minutes, then schedule the identical strategy as a live signal runner with mandate execution and a dry-run safety net.
