FTAV’s Friday charts quiz

Charts quiz regulars, you know the rules. For newbies, here are three unidentified squiggly lines. If you think you know what they show email your guesses to alphaville@ft.com, putting QUIZ in the subject line.

From the pool of correct guesses (if any) we will by midday Tuesday — because of the long weekend — select a winner. They will walk away with:

1️⃣ Enough glory to fill five and a half Olympic swimming pools;

2️⃣ A shout-out to your intelligence and judgment on FTAV (unless you expressly want to remain anonymous); and

3️⃣ An extremely desirable, limited-edition ‘I ❤️ Charts’ tee that will greatly enhance your Tinder and LinkedIn profiles, AND secure you free access to all future FTAV chart shows (if you wear it).

So here are the three charts. All are as of midday CEST on Friday, and the judge’s decision is final.

In the meantime, have a smashing weekend everybody!
