Carpenter works on the EURUSD D1 Chart. It looks for quick intraday trends and opens trades depending on the trend direction. Then it quickly modifies the stop loss at break even as soon as possible to prevent losses. If the market direction goes in its favor, it will keep the trade open until take profit is reached.
According to Backtesting results in a MetaQuotes-Demo account, from January, 2012 to September, 2014 this strategy turned $1.000 into $1.983.779,30 with a relative drawdown of 57.70% and a Profit Factor of 2.05. Similar information can be obtained by downloading a demo version and testing it on your own terminal.
I've also changed the daily amount of trade attempts up to a point where it was more profitable in the backtesting results.
