If it was this easy to earn money utilising robots, nobody would ever go to work. It is possible that robots can make money for a restricted time period, but they could start losing after awhile - and the money earned by the 'best Forex robot' with one position may disappear before you can claim it. In addition, the vast majority of robots are scalpers. They make just a few pips with every position they take - and they can set a considerably tight target. The chances of surviving with such a strategy are quite limited for a trader.
Trading on a margin can have varying consequences. It can influence your trading experience both positively and negatively, with both profits and losses potentially being seriously augmented. Your broker takes your margin deposit and then pools it with someone else's margin Forex deposits. Brokers do this in order to be able to place trades within the whole interbank network.
Forex trading is the largest market in the world, with nearly $2 trillion traded on a daily basis. There are many factors that can contribute to changes in the value of a currency. Some of these factors include terms of trade, sometimes referred to as the balance of trade, which is when there's an improvement in the terms of the trade thanks to the price of a country's exports being higher than the prices of its imports. Other facts include differences in inflation rates, which basically involve the value of the currency, and public debt, which typically occurs when foreign investors lose confidence in the economy and make fewer or no investments and leads to inflation and devaluation of the home country's currency.
In particular I would like to make the system a lot faster, since it will allow parameter searches to be carried out in a reasonable time. While Python is a great tool, it's one drawback is that it is relatively slow when compared to C/C++. Hence I will be carrying out a lot of profiling to try and improve the execution speed of both the backtest and the performance calculations.
