Two ideas - first, try to develop some method of identifying when markets are ranging, independent of your BB system signals, and only take your BB signals when this method indicates a ranging market. Second, add some kind of filter (candlesticks?) to tell you that price is reacting positively to th...

If a man speaks in a forest and his wife isn't there to hear him, is he still wrong?
No. He is 100 % right for speaking outside of said wife's earshot.

Topic: Moving Median: a better indicator than Moving Average?
Replies: 4

It doesn't surprise me at all that a moving median performs worse (Jez Liberty's blog post) than a moving average, in terms of a crossover system; the whole idea of robust in the context of a median is that it is resistant to change despite changes in the underlying data. This being the case, why wo...

Following on from techtrade89's post, another "right way" to test might be i) start with a hypothesis about how markets behave, drawn from observation, theory or experience ii) use Monte Carlo techniques to create synthetic data that have this property and then develop, test and optimise y...

If you are using an average crossover system you could compute the price tomorrow that would give a reversal signal. This price could then be used to calculate risk.

You appear to be confused by the mathematics: if your wins and losses are equal then a 50% winning probability is break even, anything less than a 50% winning probability will obviously be a net losing situation. Similarly, if your wins are twice the size of losses a 33% winning probability is break...

Maybe some form of maximum favourable excursion analysis? If testing shows that a profitable trade that has been open for 'x' period of time normally has potential for 'y' further gains, whereas a new trade on average has potential for 'z' gains, then if z > y replace the trade, if z < y don't repla...

The study makes the claim that profits accrued from TA studies are statistically indistinguishable from profits that could be expected from the null hypothesis investment strategy. It does not claim that TA studies are actually unprofitable.

You could simply unitize the total value of all investments and allocate units to investors in proportion to their initial investment(s). It would then be very easy to keep track of everything in a spreadsheet.

As a follow up to my original post I thought I would put up another graph with a slightly different entry.

Exits not more important than entries?

I am sure many are familiar with the adage that good exits are more important than entries, even to the extent that a random entry coupled with a good exit can be a viable entry/exit system. Personally I have always thought that a good entry is something worth working towards in the belief that a go...
