One place for the data every test depends on.
Market Vault stores the historical candles, broker connections and calendar data that the rest of TR-GAB consumes. Miners, Labs, Workflows and exports all read from the vault, so the quality of your research is decided here first.
Sources per platform Connect MetaTrader 5 terminals, NinjaTrader, cTrader and LEAN as independent data sources.
Candles you can audit Sync symbols and timeframes explicitly and see exactly which data each test used.
One default broker A single ambient default decides where mining, tests and exports go unless you override it.
Sources and synchronization
Each source represents a platform installation or connection with its own symbols, candles and configuration. Sync downloads candles per symbol and timeframe into the vault; the vault view shows the available range so date modes such as “days back from the last vault candle” resolve against real data.
Spread handling is per broker: use the automatic values captured from the platform, or set manual overrides per symbol when you want conservative assumptions. Symbol calibration tools help align broker-specific contract settings before exporting bots.
The default broker
The default broker (visible as a chip in the top bar, changeable from there or from Market Vault) is the ambient destination for platform actions across the product: row-level test buttons, workflow exports and bot downloads route to it unless a screen selects something else. Jobs and tests always record which source they used, so results remain attributable when you switch defaults.
Market calendar
The vault also manages the economic calendar used by Event Mining and by calendar-aware features. Install the calendar bridge, sync events, and the calendar status view shows the coverage you can mine against.
Keep research data and broker-specific data separate on purpose: mine and iterate on your research source, then confirm the survivors on the exact broker data you intend to trade. Differences between feeds are themselves information — the tester batch tools exist to measure them.
