The SPX production book — one contract per strategy — replayed against the exchange tape at one market-minute per second. The green/red line is running net P&L; the grey silhouette behind it is the capital at work (margin in use, right-hand scale), so every dollar of profit is seen against what was at stake to earn it. Dots mark entries; rings mark exits (red ring = stop).
Scale note: left axis = P&L per 1-contract-each book; right axis = concurrent margin (defined-risk structures at capped loss, single legs at portfolio-margin stress). Multiply everything linearly for larger sizes. All values net of itemized costs.
