Welcome to the options trading guide. We hope that this new initiative will over the next few months develop into a valuable resource for both new and experienced traders alike. This is YOUR guide - I am just your humble editor. There will inevitably be plenty of gaps that need to be filled and I look forward to receiving your suggestions for added or amended content which can be included into the guide. Please add them to this thread, and I’ll include ideas as appropriate into the guide. After acknowledging your contribution your posting will then be deleted to keep this thread short and confined to that of being a guide only.

1.1 Introduction
Trading options is often seen as a high risk activity, which immediately conjures up a vision of Nick Leason and the ruination of Barings Bank. In practice, trading options can be anything between exceptionally high risk and very low risk, lower in fact than trading shares or indices directly. The aim of this guide is NOT to be an options trading course, but to provide some direction to enable you to learn about this fascinating and frequently misunderstood area of trading for yourself. You will need to do lots of your own research , lots of background reading, and be prepared to work at it in the same way as you would any other form of trading venture.
1.2 Index Options
A good place to start is trading Index Options, the FTSE100 perhaps, or the S&P 500 or DOW. Index options have a number of advantages over share options, which can be summarised as follows :-
1. Does not require constant screen watching.
2. Indices tend to move more smoothly than individual shares.
3. Tend not to “spike” up or down, and if they do, normally return to the mean.
4. No take-overs or profit warnings.
5. Spikes down tend to recover, whilst shares can carry on falling to zero.
6. Monthly contracts available.
7. Tighter spreads than share options.
8. Highly liquid.
1.3 Share Options
Share options tend to offer “more bang for the buck” than index options, and also enable you to spread risk across a number of trades. Volatility will be greater than for index options, which can be a benefit if used correctly.
------------------------------------------------------------------
Aren’t options very high risk?
They certainly can be for those who do not take the time and trouble to learn to trade them with discipline and knowledge. But used correctly, the risks involved can be reduced until they are lower than if you were to trade the underlying index or share directly.
Do I have to learn all that “greeks” stuff?
A working knowledge of the main factors that affect options pricing will come with time and practice, and will definitely enhance your trading results.
So how do I get started?
1. Read a good options primer. There are many good ones out there. By choice, I would choose “Options Plain and Simple” by Lenny Jordan. Then follow that up with "Option Volatility and Pricing" by Sheldon Natenberg.
2. Use the resources of this site and the internet. There is an excellent free on-line training course run by 21st Century Education
3. Learn how to construct and interpret profit/loss pay-off diagrams. Use appropriate software. There is an excellent free plug-in to Excel97 and higher, Options Strategy Evaluation Model available from Peter Hoadley.
4. Paper-trade using free 20 min delayed data from Liffe for UK share and index options, or CBOE which is the equivalent site for share options in the US.

Volatility skew measures and accounts for the limitation found in most options pricing models and uses it to give the trader an edge in estimating an option's worth. May also be applied to account for different implied volatilities between options at the same strike price in different months

Underlying Instrument

Vega
The amount by which the price of an option changes when the volatility changes. Also referred to as volatility.
Volatility
A measure of the amount by which an underlying is expected to fluctuate in a given period of time. Volatility is a primary determinant in the valuation of options premiums and time value. There are two basic kinds of volatility, implied and historical (statistical). Implied volatility is calculated by using an option pricing model (Black-Scholes for stocks and indices and Black for futures). Historical volatility is calculated by using the standard deviation of underlying asset price changes from clos e to close trading going back 21 to 23 days.
Volatility Skew
The theory that options that are deeply out-of-the-money tend to have higher implied volatility levels than at-the-money options. Volatility skew measures and accounts for the limitation found in most options pricing models and uses it to give the trader an edge in estimating an option's worth. May also be applied to account for different implied volatilities between options at the same strike price in different months
