There are some restrictions on company buybacks, mostly based on average daily volume.

Investopedia explains Rule 10b-18
The rule breaks down as follows:

* Manner of purchase: The issuer or affiliate must purchase all shares from a single broker or deal during a single day.
* Timing: An issuer with an average trading volume less than $1 million per day or a public float value below $150 million is unable to trade within the last 30 minutes of trading. Companies with higher average-trading-volume or public float value can trade up until the last 10 minutes.
* Price: The issuer must repurchase at a price that does not exceed the highest independent bid or the last transaction price quoted.
* Volume: The issuer can't purchase more than 25% of the average daily volume.
