chill! 😊 Flash crash means that the price drops and then jumps back to its previous value. Chart does show that there was a crash that did took place but the whole action happened inside 2min timeframe and after that price recovered and business as usual. If you didn't had sell order in place than you have nothing to worry! 😉
Oh okay... thanx...
Aftermaths, I read an article which was saying that it was an error in the backend code...
