In my trading software I write myself logs like this:

- First column is time (it's so big because this is number of ticks elapsed from 1970 where one tick = 100 nanoseconds, just don't worry about that)
- Second column is operation. Either q for quote b for buy and s for sell.
- Third column is price.
Lines with the same
time should form a vertical
candle. Also I need to add annotations on the graph to show where I buy and sell stocks.
Without annotations I think this task is trivial for Matlab, but can I add annotations in Matlab? i.e. I want to have something like this:
When I buy stock I want to display a green arrow and when I sell stock I want to display a red arrow. It's OK to use other symbols until they are clear and distinguishable.
