Hi,

I am relatively new to Bitcoin trading and there is something I would like to ask the opinion of experienced traders about.

I keep watching a few exchanges during the day and sometimes I notice a sudden upward or downward price spike. For example, let's say the BTC price is fluctuating mildly around 7340 in the range of 7330 - 7350, and all of a sudden, the price instantly jumps up to 7480, and then drops back to 7340 range pretty quickly. Same with downward spikes, for example the price instantly jumps down to 7210 and then goes back up quickly. This does not happen frequently but it grabbed my attention.

Any ideas what might be causing this behavior? A huge buy/sell order? Some manual manipulation on the exchange side?

Thanks.
