This discussion topic is motivated by a friend..- well, we have not actually met yet, we got acquainted via email, currently he is on a mission away from home for 3 months, but with lots of questions on his mind. For you, my friend - something to keep you busy through the lonely afternoons. For anyone else following this, you are of course most welcome to participate...
I'll use this discussion topic to show a couple of trades involving trading in the straight futures - (such as what anyone who got involved in currency trading for example, would be very familiar with) - versus trading with various different options positions. You then judge which is the more risky approach?
First off, I'll use two graphs from out of the Options Explorer on all these posts, as follows:

The graph on the LEFT is a profit / loss graph. It shows us the profit / loss that you will make on the left axis, versus the price of the commodity (or instrument) that you are trading in on the bottom axis. The
RED LINE will be the profit / loss situation on the day that the futures instrument expires - in this example 21 days from today. The
BLUE LINE is the profit / loss situation on the day that you entered the position (in other words today). The
PURPLE LINE is the profit / loss line on an arbitrary date into the future - in this case it is 9 days into the trade. Thus the profit / loss line is time dependant (naturally, since the price of the commodity will change over time). The vertical bars are the prices at which we entered individual positions. The solid vertical line represents the price on the day that we are analysing - in this case day 9, the price is at 145, you can read the profit from out of our graph on this day from the purple line.
The graph on the RIGHT presents exactly the same information, but in this case it super-imposes the profit loss in our trade position on top of a line chart of the daily closing price of the underlying commodity (price chart in
GREEN). Our profit / loss lines are drawn in
YELLOW. The thick (bold) yellow line is our break-even lines (
in this case, between the two thick yellow lines we are making a profit, outside that area we are making a loss - note sometimes this will be reversed, and sometimes there will only be one line. The feint yellow lines tells you on which side of the break-even line we are in trouble, obviously on the other side we are in profit). The two feint yellow lines represent loss lines - in this case a $500 loss and a $1000 loss respectively. Futures price on the left axis, days left until the futures expires on the bottom axis. We are able to simulate price action on this graph - I have added nine days on this graph, keeping the price constant at 145. Thus this graph shows we are in profit (9 days in if the price stays level) and the graph on the left shows us how big that profit is (about $700 - pink line at a price of 145)
These graphs shows you the underlying risk in a trade situation - how much money can you make and how much can you loose, and what does the price of the instrument you are trading in have to do for you to make a profit, versus for you to make a loss. (
In the example above (USD/GBP) it should be clear that we are expecting the price to stay level - if that happens we will be making a profit.)
Study and familiarise yourself with these graphs - we will be using them to describe different positions.
