Actual for You - Don't Expect Too Much From Expectation!
Internet Business-in-a-Box: Too Good to be True? es to total trades (P)What could be bad? You've seen the ads: Get your own website. For FREE! Get a turnkey Internet business. For FREE! Get a truckload of marketing materials. For FREE! Start making money from home TODAY. Capital WOW!Yes, it's true: those business-in-a-box people may really give you a turnkey business opportunity that won't cost you a dime. That is, it won't cost you a dime to have Average $ value of a winning trade. (W) To calculate E, apply the formula: E = ((1+W/L)*P) -1 For example:- Suppose 100 trades produce the following results: 40 winning trades total $40,000 (W=1,000) P= 40% and W/L = 1,000/500 = 2 Web accessibility for screen magnifier users What does 'Expectation' tell you about your trading system?The needs of screen magnifier users are overlooked when implementing web accessibility on to a website. Screen magnifiers are used by partially sighted web users to increase the size of on-screen elements. Some users will magnify the screen so that only three to four words are able to appear on the screen at any one time. You can try using a screen magnifier yourself by downloading the Zoomtext sc A positive expectation number, generated by your system rules can tell you if your system appears capable of producing a profitable trading outcome. No system will deliver a profit unless its rules show a positive expectation. The two elements used to calculate expectation: Win probability - (Often Referred to as Accuracy). The percentage of all winning trades of the total number of trades made. Accuracy sounds very important but it can usually be increased by 'buying more certainty' and that could cost you dearly. Waiting longer for a market to develop in order to improve your accuracy percentage will almost certainly limit your trading options and your potential for achieving good results. But it's end results not accuracy that matters. Therefore arguments for the merits of accuracy should be politely disregarded. Win/Loss Ratio The average size of a win produced by your rules, divided by the average size of a losing trade, produces this useful ratio which can indicate whether you are letting your winning trades run and cutting your losing trades. Whatever is revealed, it will not satisfy the commodity system trader - who will want to know if a good looking ratio should have been even better. Using a simple formula, these two elements produce the expectation value 'E'. Calculating the Expectation Value: List all the trades made in the test period and extract the following: Percentage of winning trades to total trades (P) To calculate E, apply the formula: E = ((1+W/L)*P) -1 For example:- Suppose 100 trades produce the following results: 40 winning trades total $40,000 (W=1,000) P= 40% and W/L = 1,000/500 = 2 The percentage of all winning trades of the total number of trades made.

system trader - who will want to know if a good looking
ratio should have been even better. Using a simple formula, these two elements produce the
expectation value 'E'. Calculating the Expectation Value: List all the trades made in the test period and extract the
following: Percentage of winning trades to total trades (P) To calculate E, apply the formula: E = ((1+W/L)*P) -1 For example:- Suppose 100 trades produce the following results: 40 winning trades total $40,000 (W=1,000) P= 40% and W/L = 1,000/500 = 2 To calculate E, apply the formula: E = ((1+W/L)*P) -1 For example:- Suppose 100 trades produce the following results: 40 winning trades total $40,000 (W=1,000) P= 40% and W/L = 1,000/500 = 2 E = ((1+2)*40%) -1 = 0.2 E therefore shows a positive value of 0.2 Think of expectation simply as a seed with potential for
growth. In the same way as many seeds have potential for
growth, so do many system rules show positive expectation.
No big deal here then. But in the right hands things could take off. Successful
commodity system traders know a thing or two about getting
the best out of their rules. The three " big boys" - market selection, risk management
and money management supply the key to cultivating the seed
of expectation to produce massive multiplied gains. These
activities go under the global title of trade management. With their comprehensive methods, employing risk resonance
testing and expert trade management, successful system
traders can discover the potential of any rules to meet
their trading goals. These professional traders bypass the subject of expectation
altogether - expectation provides no information about the
potential of their systems. So, don't expect too much in return for studying
expectation. Study the methods of the successful traders instead.
