The lmt (low maintenance trading) forex formula is a piece of software that you attach to your (free) metatrader trading platform. The lmt is a trending system. What that means is when the markets are moving up or down over a period of time it is known as a trend. The lmt gives an alarm signal at the close of a 4 hour or daily chart, advising you of a trading opportunity. You then use some discretion & follow the trade signal; buy, stop loss & targets are all provided by the software. (I can explain in greater detail later if you would like to know what I mean).
In any kind of trading, trading with the trend is the most conservatiove method to follow. From february to july the markets trended on many pairs and the lmt performed brilliantly (80%+ successful trades). During the 6 weeks (it seems so much longer

) summer holiday period the markets went sideways (its normal at this time of year) and the lmt doesn't work. This is normal for a trend following system.
We are waiting now (end of august) for the big boys (banks & hedgefund traders) to return to the markets and trends to be re-established. This should then carry on until christmas when the markets will take another breather. For a more in-depth explanation of the Lmt forex trading system
