What is PaperPoly?
A new virtual portfolio starts with $1,000. The product states that prices refresh every 30 seconds and that simulated fills consider bid and ask rather than only a midpoint. This supports a more structured practice routine, but modeled fills and the refresh interval still differ from live order-book execution.
Review PnL, ROI, win rate and open-position value alongside the number of resolved bets behind each rate. A journal retains the reasoning for a position, while MCP lets an assistant search, place paper bets and retrieve statistics. Graduate certification uses the provider’s resolved-bet, duration and win-rate/ROI requirements; it is not an accredited qualification.
Who it is for
