OverlaySync Pro
Overview
OverlaySync Pro lets you overlay any symbol's candles directly on your current chart with a single click. See how two instruments move together in real time — with automatic scaling, time synchronization, and Pearson correlation analysis.
Perfect for correlation trading, hedging analysis, and spotting divergences between related instruments.
One-Click Symbol Switching
The panel shows 30 instruments organized across 3 pages. Just click any symbol — the overlay switches instantly:
Page 1 — Forex Majors: EURUSD, GBPUSD, USDJPY, USDCHF, AUDUSD, NZDUSD, USDCAD, EURGBP, EURJPY, GBPJPY
Page 2 — Forex Crosses: EURAUD, GBPAUD, AUDJPY, CADJPY, CHFJPY, NZDJPY, EURCAD, GBPCAD, EURNZD, AUDCAD
Page 3 — Metals & Indices: GOLD, SILVER, BITCOIN, ETHEREUM, NASDAQ, S&P 500, DOW 30, OIL, DAX 40, FTSE 100
Navigate with [Next >>] and [<< Prev] buttons. Active symbol highlighted in blue. Unavailable symbols marked [N/A].
Smart Symbol Detection
Automatically detects your broker's naming convention. For each instrument it tries multiple name variants — for example, Gold is searched as: XAUUSD, GOLD, XAU — each with and without your broker's suffix. Works with virtually any broker.
Full Chart Coverage
The overlay covers the entire visible chart area. Candles are synchronized by time using exact bar matching, so the overlay always lines up correctly even when instruments have different trading hours.
Pearson Correlation
Real-time correlation coefficient calculated from price returns:
- +0.7 to +1.0 — STRONG positive (move together)
- +0.4 to +0.7 — MODERATE positive
- -0.4 to -0.7 — MODERATE negative
- -0.7 to -1.0 — STRONG negative (move opposite)
Invert Mode
Click [INV] to flip the overlay upside-down — useful for negatively correlated pairs.
