About this app

Set target weights and a relative band, enter what you actually hold, and see which positions have drifted outside their tolerance and the exact trade to bring each back. Explains the difference between relative and absolute bands — a 5% relative band allows 57 to 63 on a 60% target but only 4.75 to 5.25 on a 5% one, which is usually what people mean and rarely what they configure.
