Trading System: What Is It and Is It Important?
What Is Trading System?A trading system is a systematic system or a set of rules which should be able to answer the following questions:a) What stock to enter.b) When to enter (Entry strategy).c) How much to enter per position (This is called position sizing, or money management, or bet size).This is meant to limit the size of what you are prepared to lose / risk in any single trade to a percentage of your total trading capital (risk management). If you risk too little per trade, you win little, and hence it will take much longer time to grow your...

The Psychological Need To Be Right vs. Making Money
In my previous post, I picked one simple example from the book Trade Your Way to Financial Freedom by Dr. Van K. Tharp to illustrate that being right does not necessarily mean making money.Yes, in trading, you can be right most of the time, yet still lose money in the end. On the other hand, you can be wrong most of the time, but still making money over the long run. It depends on “how much” you gain when you’re right & how much you lose when...

Historical Volatility (HV) vs. Implied Volatility (IV): Definition
WHAT IS VOLATILITY?Volatility is a measure of risk / uncertainty of the underlying stock price of an option. It reflects the tendency of the underlying stock price of an option to fluctuate either up or down. Volatility can only suggest the magnitude to the fluctuation, not the direction of the movement of the price.In options, there are 2 types of volatility:1) Historical Volatility (HV), or sometimes called Statistical Volatility (SV): A measure of the fluctuations of the stock price over the past 30 trading days.Therefore, when there is a sharp...

Why Being Right In Your Trading Does Not Necessarily Mean Making Money
I like the discussion in Corey’s Afraid To Trade blog some time ago on the topic of “Should I trade to be right or should I trade to make money?”"Being right" does not necessarily mean "making money". In that post, Corey also gives some examples why it is so. But what interests me more is the discussion in the comments of that post, in conjunction with the post from Chris Perruna on “Position Sizing and Expectancy”.The discussion in that post has...

If that's your goal you probably struggle with it a lot. But all of the following tend to work.If you goal is to be a great trader, then you probably will do well.If you goal is to use trading as a way to measure your self-development, then you will probably do well.If you...

How To Determine Options Liquidity?
Quite often I read articles which tell us that options liquidity can be measured by open interest. Because when options have high open interest, this means there are more people interested in the trade, and as a result, it’s more likely for us to get a better pricing for the trade.Yes, this is quite true. Normally, the higher the open interest, the more likely we’ll be to trade that option at a narrower spread between bid & ask prices. On the other hand, the lower the open interest, usually there will be a wide spread between bid & ask...
