Is it the same as your trading platform? Huge volatility in an instant will have a bad influence on trading. Orders that you don't want to trigger, stop losses that you don't want to trigger, are suddenly triggered. Cause a terrible loss to yourself.
This could possibly be because of bad broker data i trade EURUSD everyday and haven't seen such fluctuation in price you can compare your chats on Trading view, you have 2 brokers there FXCM and OANDA
