FTAV’s Friday charts quiz

For those of you who missed yesterday’s pub quiz — or simply cannot get enough of lines-based fun — here’s this week’s charts quiz.

Identify what’s shown by the three charts below and email your answers to alphaville@ft.com with “Quiz” in the subject line. If your guess is right and arrives before midday(ish) Monday, and you could win a very fetch T-shirt.

We usually name those who get the answers correct, so if you want to remain anonymous, let us know. Godspeed.
