Start date of charts and info on Coinmarketcap

[CryptoAlphaStar]

Hi guys,
does CMC charts starts from the first day a coin is traded ever on an exchange or do they start from the day the coin is added to CMC?

For example, there is an ICO. After the ICO the coin is listed on HitBTC and trades there for 2 weeks. After that it is added to CMC. 2 months time pass. And we look at the chart and stats for the coin. Is the first day the day it was added on CMC or the day it was added to HitBTC?

Usually Coinmarketcap are adding coins by requests and after they passes 1BTC daily volume.
So, the answer of your question is - NO. The in on Coinmarketcap is from the first day added there, not the first date the coin hit the markets.
