A signal marketplace needs a trading journal first
The marketplace layer only becomes useful when every signal can be inspected, grouped, filtered, and audited through a durable journal.
Journal before marketplace
A signal marketplace sounds exciting, but the less glamorous trading journal has to come first.
Without a journal, a signal is just a notification. With a journal, it becomes a record that can be filtered by strategy, symbol, timeframe, side, entry, exit, and lifecycle state.
That record is what makes later marketplace features trustworthy. People need to see the history, not just the pitch.
The strategy is the boundary
Quantarya treats a strategy as the core boundary for routing and review.
A strategy can represent one TradingView setup, one execution system, one account family, or one research idea. The exact meaning is flexible, but the boundary should stay clear.
That is why strategy metadata matters: the ID is for machines, while the title, description, tags, image, and organization are for humans trying to understand what they are looking at.
Auditability is not optional
Manual cleanup can be necessary, but it should not silently rewrite reality.
Quantarya keeps manipulation visible through retained audit rows and warnings when too many recent edits, closes, or deletes happen.
That rule is simple: if a strategy is clean for a while, the warning fades. If it needs constant cleaning, users should know before trusting the numbers.
