Bad Data Spikes

How are bad data spikes dealt with and how often do the happen? I’m new here and my stradagy has been running for a few months and so far I have had a few 1 min spikes or drops that did not exists. The data fixes itself with in a min or two but it causes my drawdown to look bad. Is this common?

Looks like the spke has been fixed, sent in a help request and it was fixed with in a day… I guess I answered by own question.
