Margin is one of the most important concepts of Forex trading. However, a lot of people don't understand its significance, or simply misunderstand the term. A Forex margin is basically a good faith deposit that is needed to maintain open positions. A margin is not a fee or a transaction cost, but instead, a portion of your account equity set aside and assigned as a margin deposit.
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.
Inflation Rates: Countries with inflation rates that are lower than other countries experience increased currency values. These increases mean that the purchasing power has also increased. The country that previously spent $1 million for 10,000 units of a foreign product is now able to purchase 18,000 units with the same $1 million, or $750,000 for the same 10,000 units. High inflation rates mean that there will likely be depreciation in the value of the currency.
Margin requirements for futures and futures options are established by each exchange through a calculation algorithm known as SPAN margining. SPAN (Standard Portfolio Analysis of Risk) evaluates overall portfolio risk by calculating the worst possible loss that a portfolio of derivative and physical instruments might reasonably incur over a specified time period (typically one trading day.) This is done by computing the gains and losses that the portfolio would incur under different market conditions. The most important part of the SPAN methodology is the SPAN risk array, a set of numeric values that indicate how a particular contract will gain or lose value under various conditions. Each condition is called a risk scenario. The numeric value for each risk scenario represents the gain or loss that that particular contract will experience for a particular combination of price (or underlying price) change, volatility change, and decrease in time to expiration.
Trading on margin can be a profitable Forex strategy, but it is important to understand all the possible risks. You should make sure you know how your margin account operates, and be sure to read the margin agreement between you and your selected broker. If there is anything you are unclear about in your agreement, ask questions and make sure everything is clear.
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.
