GBY tracks a private portfolio held at Interactive Brokers, measures how far it has drifted from its plan, and records what its indicators said — then grades those signals against what actually happened. Every number here is computed from prices that have already occurred.
Nothing on this site forecasts prices, and nothing here is an offer, an invitation or advice. Private tool, one account, own money only. Not authorised by the Financial Conduct Authority.

Connects to IB Gateway, pulls positions, cash and prices. Read-only — it cannot place an order.
Compares each holding against its target. Past a band you set, it works out the trades that would correct it.
Writes down what the indicators said, then grades each one 1, 5 and 20 days later against the actual price.
A WhatsApp message when a holding leaves its band or a drawdown tier fires. You decide whether to act.
