Experiments & Spreadbetting 27 Mar 2007 01:44 am

Okay, it took a bit longer for me to define a strategy for this project. And I didn’t want to start using the spreadbetting account without it on Monday. Blind betting without a clear strategy is gambling, very dangeroug gambling…

On the other hand, starting one day later means that I will lose all my money one day later, too, right? :-)

1. Spreadbetting basics

First of all, I have looked up the spreadbetting basics. Apart from the info from Wikipedia, ETrade has also got a nice guide about the matter. It works much easier as I thought:

Let’s take as a betting target the DAX (german stock index). In the spreadbetting account you see 2 prices for DAX: BID and ASK. You always buy at ASK price and sell ad BID. In DAX, the difference between bid and ask are 2 points (in ETrade).

Example:

(6874-6876) Bid-Ask

Now, if you think that the prices are going up, you buy at ask price. And after the index rose X points, you cash out by closing the position: you sell at bid price.

Example:

- We bet $5 at 6874-6876 that the prices will go up (buy $5 at 6876).
- The prices rose to 6880-6882 and you decide to cash out (sell 5$ at 6880).
- Therefore, you have won $20 (6880 minus 6876 = 4. And 4 times $5 = $20).

Notice, that, in fact, DAX rose 6 points, but you only got paid for 4. The 2 points of the bid-ask “spread” are kind of “commission” the spreadbetting company gets. So, in the example above, if you buy at 6876, the index has to rise at least 2 points just to break even.

The bid for falling prices works just the same: you SELL at BID price, and you BUY at ASK to close the position later.

2. Defining the rules:

The essence of steady, constant progress is moderation: an equilibrium between risk and opportunity. It is better to go slow, but steady than to speed up and hit a wall at the end. Even in such a risky and volatile investment product like financial spreadbetting you can minimize a lot of risks by limiting yourself with a few pre-defined rules :-) Here are mine: 

  • I will only be concentrating on one index: DAX
  • I will play rising courses only. Playing both can be confusing and confusion is very risky. Therefore,
  • confusion is our enemy. It gets you out of control. Avoid it by always knowing what you do. If you are not 80% sure, then don’t.
  • Bet only few times/day. Less betting minimizes the risk of losing!:-) 1-2 times a day is more than enough. If you bet more, first, it is much more probable that you will hit a huge price spike/fall and lose all your money and, second, playing more affects you psychologically and can lead to unlogical, very subjective and, therefore, very risky decisions.
  • Have an objective primary strategy that you follow (with small variations depending on the current situation).

So, these were my 5 limitation rules, like speed signs on a highway. Before defining a strategy, I needed a theory based on past experience, though. In other words, I had to study the past DAX behaviour and then do a strategy.

I will publish my findings in the next post. Gotta go.

For now, farewell.

Experiments & Spreadbetting 24 Mar 2007 11:38 am

Financial spreadbetting is the most risky, volatile and speculative way there is to make profit in the financial world. It’s more like betting in the casino or in a horse race. In fact, the profit You make with spreadbetting is tax-free in the UK. I don’t know whether it is the same in the US.

While trying to make profit with financial gambling is like playing russian roulette, I have decided to try myself in this area and report the outcome. After all, I have a decent knowledge about the market, investing and statistical calculations. And, like in casino and horse races, knowledge is what makes the risk/chance relation to work in player’s favor.

For this purpose I have opened an account at ETrade Spreadbetting with an initial deposit of 150€. That’s the max I can afford to lose on this project for the sake of the science! :-)

I have also chosen to play real money instead of demo account mainly because of two reasons:

  • First, we humans tend to make different choices when it comes down to the “real thing”. It is like playing poker: You would probably play more conservatively with the real cash bets. For this project, I have decided to make it as real as possible and, therefore, play real.
  • Second, should I win something, I would hate not being able to withdraw my winnings just because I have chosen to play a goddamn demo.

As I never did spreadbetting before, the first step will be to investigate and learn the basics. Then, I will have to chose which stock/index to play, study it and develop a sound strategy. Lastly, I will play my strategy and pray that it works and doesn’t affect my objective thinking.

Results and updates to follow, stay tuned!
