what does a real long thin line after a bar mean?

You see a regular red or green bar but then a long thin line extending below.

sometimes you have small squarish bars with two thin lines one on the top and one on the bottom.

 

What type of chart?

 

it is the candlestick chart from etrade pro. I have it set to 1 minute period.

I also noticed that later , GE is trading at the price where the long thin bar touched .

At 1:15 the thin bar touched 13.25 traded 13.36

then 1:23 it actually traded at that price of 13.25

 

It designates the open, high, low and close for the bar.

I really hope you have a lot of money.

5yr

 

it means you are taking part in a pub crawl.

 

the elusive 'double tail'. That's a lay-up.

 

it is maximal and minimal price for this period.

 

I am only trading 52K right now, I bought puts as a safety net just in case if I mess up.

I only daytrade or swingtrade GE

 

give him a break. mad money only shows him line charts. how is he expected to know???
