TradeOnyx fetches the S&P 500 (^GSPC) year-to-date return from Yahoo Finance once per calendar day and shows it as a KPI tile in the Overview, exclusively when the period filter is set to Year. Below the SPX number, a delta line ("Δ +2.3% vs your YTD") makes the comparison explicit. The delta colour is green when you're outperforming the market, red when you're trailing.
The S&P 500 is the most widely-tracked passive equity benchmark for retail USD-denominated capital. It's not a perfect comparison for an FX trader or a crypto specialist, but it's the universal opportunity-cost yardstick: every dollar you're trading is a dollar you could have parked in an SPX ETF, and that ETF's return is the floor your active strategy needs to clear to justify the time, stress, tax friction, and platform fees.
April 30. ^GSPC closed at 5,250 today; year-start (Jan 2) close was 4,900. Your TradeOnyx YTD = 9.5%.
The honest reading depends on the magnitude: - Beating SPX by < 2% — within noise. Active management costs more than 2% in time + tax + fees over a year for most traders. This is breakeven against passive. - Beating SPX by 2-5% — meaningful. You're earning the active premium. - Beating SPX by 5%+ — strong. The strategy has real edge, not just market beta. - Trailing SPX (negative delta) — the active management isn't paying. The honest follow-up: am I doing this for income or for the activity? If for income, simplifying to the passive index is the rational move. - Negative absolute YTD with green delta — bear-market year. You're down less than the index. Still useful — capital preservation in a bad year is a real outcome. - Positive absolute YTD with red delta — bull-market year. You made money but the index made more without you trading at all. The classic active-management trap.
Note: the comparison is most fair on USD-denominated capital with US-equity-like exposure. FX-only or commodity-only traders can use it as a baseline rather than a strict apples-to-apples — the key signal is still "am I beating the easiest passive alternative my capital had?"
TradeOnyx renders the S&P 500 YTD only on the Overview tab, only when the period filter is Year. Shorter windows would compare your one-week return to the index's one-week move, which is dominated by noise on both sides. The yearly window is the smallest one where the comparison gives signal.
The colour split is intentional: the SPX value's own colour reflects whether the market is up or down (green/red on its own sign), while the delta hint colour reflects the trader-vs-market comparison (green when you outperform, red when you trail). A bear-market year where you're down less than the index reads as red value, green hint — and that's the right cue. The market's bad year is still bad; you're just losing less.
The most rational use is once per quarter, when the noise has had time to wash out. Open Overview, switch period to Year, read the Annualized tile + the SPX YTD tile next to each other. If your annualized projection trails the SPX YTD, write a one-line journal entry: am I beating the market on a meaningful margin, or am I just trading because I like trading? The data forces the question whether you want it to or not — that's its job.
