I new to trading and I would like to know why the graph of the stock after closing still follows a path up and down and why it is not a straight line.
Can I trade using on the weekend using the gray graph shown?
Is there any significance of this path/graph in the after hours? Does it affect anything or offer anything valuable that I can use to some advantage?
In the US, pre-market trading is from 4 a.m. to 9:30 a.m. EST and after-hours trading is from 4 p.m. to 8 p.m. on weekdays. Some collectively call both after hours trading.
Some brokers do not offer after hours trading. For those that do, it often requires that you get approval to do so, usually just a formality.
After hours trading tends to be more volatile with larger bid/ask spreads due to illiquidity. You need to be quick thinking and decisive because price can turn on a dime.
