The most profitable advisor of the Good Martin System
The Good Martin System Expert Advisor is a fully automated trading system that operates without any
human intervention. As you might guess, this expert advisor is a pure martingale system, using no indicators to enter positions. However, testing has shown that it has proven to be the most profitable of all the systems tested.
The most profitable advisor opens its first order following the price. The expert advisor will open the order in the direction the price moves when it's placed. If the trade goes against us, the expert advisor will double the initial lot, attempting to offset a series of losing orders with a single profitable position.
To use the trading expert advisor, you need to install it in the Meta Trader4 trading terminal. To do this, download the archive with the advisor and, in the open data directory via your terminal, place it in a folder named "expert." Then, restart the platform. After launching, go to the list of advisors and drag the expert advisor named "Good Martin System" onto the screen.
The developer of this miracle claims to use a 15-minute chart and the EUR/USD currency pair. In reality, this expert advisor can work on any currency pair , but it's worth running it in the strategy tester before using it.
Setting up the most profitable advisor.
Since the EA doesn't use any indicators for entering Forex positions, the author left only the money management settings open. The "lot" line specifies the initial lot with which the EA will enter the market. The "Factor Lot" line is a multiplier for the next lot in the event of a losing position. In the "Distance Order" line, you can change the distance between orders in pips if the martingale triggers. In the "Take Profit" line, you can set the desired profit. The "Magic Number" function assigns a special number to positions opened by the EA. This ensures that it doesn't touch orders opened either manually or by another EA.
Initially, I decided to test the advisor with the default settings. The EUR/USD currency pair was analyzed for the period from January 1, 2015, to May 21, 2015. The test results are shown in the image below:
The profitability was 90% of the deposit, but the drawdown was also similarly large. For those deciding to try the demo account, I recommend reducing the lot size from 0.1 to 0.05 for a $100 deposit. I decided to run a second test with the same settings, but on the GBP/USD currency pair. The test period was from January 1, 2015, to May 21, 2015. The test results are shown in the image below:

On the GBP/USD currency pair, the EA was on the verge of losing money several times, so before using it, the settings need to be optimized. For optimization, I recommend testing with the order distance, trading lot size, and multiplier parameters.
The advisor has a high potential profitability, but unfortunately, the risks are corresponding. I recommend trading only on a cent account and with money you can afford to lose. Recommended brokers for this are RoboForex or Amarkets , the latter of which offers its own free advisors. Thank you for your attention, and good luck!
