The occasional profit foregone because the trailing stop algorithm has stopped out the trade too early, which becomes apparent in hindsight, is nothing more or less than the cost of doing business. All it means in reality is that you must be constantly testing, testing, testing and, very importantly, doing this over extended periods. 49 During the course of the week starting on Monday August 6 2012 and ending on Friday August 10 2012 the Omicron Forex breakout algorithm made five trades. It could have made more but it is programmed to refrain from new trades when there are currently open positions under management.

These announcements take place on what has become known as Fed Day, which occurs about 11 times per year, and is always scheduled well in advance. “No change” on this occasion did not prevent large spikes in opposite directions in the EUR/USD pair immediately after the announcement.

It was known that the announcement was coming up, and when, and also the tendency of the market to behave in the way it did on such occasions.

You need to be able to see prices changing in the historical tester. You need to be able to change the strategy parameters, one by one, and note the effect it has on the outcome over a significant period of time, much more than a few days or a month. You must train yourself to recognise and avoid the phenomenon of curve-fitting, which means allowing yourself to be convinced that changes made that are effective in the short term can be extrapolated to the longer term. They cannot. The historical tester allows for back-testing to be done in visual mode, when activity is so speeded up that 30 minute bars can open and close in seconds.
