Jack Signals - GC Bridge [JOAT]XAU SPOT GOLD FUTURES BRIDGE
Most gold analysis, levels and signals are quoted in XAUUSD spot . A large number of traders execute in GC or MGC futures . Those two markets do not print the same number, and the difference between them is not a constant you can memorise.
That difference is the basis : cost of carry plus time to expiry. It drifts through the session, widens as a contract ages, and jumps at the roll. A December contract can sit $60 above spot while the front month sits $10 above. Any fixed offset is wrong the moment you change contract, and quietly wrong every day in between.
This indicator puts spot onto the futures chart and translates in both directions, live.
[bWHAT IT DRAWS
Live spot line across the entire chart, with a price tag pinned to the last bar
Ghost spot candles — real XAUUSD OHLC, so you see how spot is moving, not only where it is
Price tag on the futures candles carrying their spot equivalent
Fair-value line — spot plus the mean basis, i.e. where futures would trade if the spread were behaving
Session high and low , labelled in both units
Liquidity levels from swing pivots, marked SWEPT once taken
───────────── READING FUTURES BACK IN SPOT ─────────────
The reverse conversion is the one used most. You are looking at a wick on the futures chart and your level is written in spot. Every level is labelled with both prices, so "did that sweep reach 4453 spot?" becomes readable instead of a calculation.
───────────── THE BASIS IS Z-SCORED ─────────────
This is the part that is not just arithmetic.
The spread is measured against its own recent behaviour:
z = (basis − mean(basis)) / stdev(basis)
A fixed tolerance such as "warn if the basis moves more than $1.50" is the wrong test, because how far the basis normally moves is itself not constant. Normalising it against its own standard deviation is.
When the spread is stretched beyond your threshold, the dashboard flags it and level conversion falls back to the mean basis instead of the live one. This is not decoration: convert a stop at a three-sigma basis and you have baked a temporary distortion into it, so when the spread reverts your stop sits in the wrong place. The fair-value line makes the same thing visible — when candles pull away from it, the spread is moving, not gold.
───────────── OPTIONAL: CONVERT A FULL SETUP ─────────────
Enter two entries, a stop and three targets in spot, and it draws them on the futures chart at the converted prices, each labelled with both numbers. Leave them at zero and those rows disappear entirely — the live mirror works on its own with nothing filled in.
With a setup loaded it also sizes the position. Enter account size and risk percent and it returns a contract count from the real tick value, warns when a single stop-out would consume more than half a daily loss limit, and states plainly when the answer is that the trade does not fit the account.
A useful identity: gold levels are commonly quoted in 0.10 increments, which is exactly one COMEX gold tick. An 80-pip stop is 80 ticks — $800 per GC contract, $80 per MGC . No conversion, no rounding.
There is also an optional ATR trailing stop for a runner leg, armed when price reaches a chosen target.
───────────── NOTES AND LIMITATIONS ─────────────
The basis is read off the chart symbol , so it is correct on GC1!, any dated contract, and MGC with nothing to configure
Ghost candles inherit the futures session. During hours when spot trades and futures do not, there is no bar to draw them on
Pivots confirm N bars after forming. That is the definition of a swing, not a lag in the script
The displayed basis is smoothed to stop two independently-ticking feeds flickering. The reverse conversion deliberately uses the raw basis so the futures readout and the spot readout can never disagree
Default settings draw only the spot line, ghost candles and the two price tags. Levels and liquidity are switched off so the chart stays clean — turn them on individually
This indicator generates no buy or sell signals and has no view on direction. It converts prices between two related instruments, sizes a position, and can trail a runner.
Nothing here is financial advice, and no performance is claimed or implied. Test on a simulated account before risking money.
