Model setup
Saved books · real daily closes
Portfolio
Build a book in Portfolio Lab or Portfolio Studio first, then model it here.
Quant engine
Idle
Pick a saved book and run the model. The engine pulls real daily closes for every holding, walks the book with your rebalance schedule, then calibrates a return process off the realized portfolio curve and simulates it forward — with a walk-forward check that scores how honest the forecast has been.
