In automated trading, a programmer can code and give simple signals centered on the indicator where to enter and quit and have it analyzed against historical data. As opposed to auto trading, discretionary dealers have a harder job of obtaining to be as objective in observing and identifying where the access or exit signals take place, then writing it down and later figuring out the overall performance of therapy. 

The testing of the strategy in a conventional and even unscientific way can be extremely arduous and time-consuming job. It really is especially frustrating when there are numerous indicators and strategies open to go and confirm each for its potential in making profits that it’s disheartening to go through therapy one by one. Just that thought would entice the investor to adopt the shortcut.

1 way to do this is testing it by demo/paper trading. For a couple of weeks with a twenty-something or thirty-something trades, he would have recommended how it works, how much it makes or loss. If this individual thinks it’s ready for real trading, they can start. The only problem is that the strategy has only seen a current market condition, it may work in the next several months, but when a new market condition emerges, such as from an uptrend to a consolidation stage, this may produce a period of deficits, which may lead to big drawdowns. Only using the demo trading might not exactly be enough. Plus the sampling size is so small to have enough judgment on the abilities of the performance results.

Going the opposite way, a trader may make a decision to backtest with historical data and review the possible profitability of the strategy. This might become a great way since the historical data provide more than satisfactory periods of time, normally in years. The sampling size may be in the hundreds of trades, with it in various sorts of market conditions. With this sort and enormity of research, this would be more than sufficient to make a decision that there can be without doubt profitable once is actually placed in real trading right? Wrong, historical data in charts do not completely represent what and how it looks like instantly trading, no matter how accurate the data is. There are numerous elements where the data was “cleaned” or “corrected. ” It only happens following your fact. Yet the biggest hidden factor are the indicator: indications are in regular current motion. In backtesting, the indications are already sleeping in place and this eyeballing old data recover indication with historical data is like “shooting fish in a barrel, ” rather than shooting fish in the ocean. It is well known that indicators delay so when the data is already shown and known, the indicators would show what it would have been like look like in real time. But which is not the case when the real data is still unfinished. This is one reason why many online trading systems tested against historical data fail in real time, automated or discretionary.
