Higher price when purchasing then shown?

[reqehjmf12]

I was watching the trends of a certain stock and the price started to fall, so I purchased. The part I do not understand is the stock price showed $17.30, but when I confirmed the purchase, the price was actually $17.43. What would cause this? Does the bid/ask price have anything to do with it? When I looked at the price chart I never saw an influx in the price from $17.30.

Any insight would be appreciated.

It sounds like you put in a "Market" order instead of a "Limit" order. Are you familiar with the difference?

No, I am not to be honest. This is only my second day purchasing. I am using robinhood and went through their process of buying.

Is there any advantages/disadvantages to either?
