Open positions are required to be fully margined at all times. FOREX.com does not engage in margin calls; you are responsible for monitoring your account and maintaining 100% of required margin at all times to support your open positions. To help limit your trading losses and ensure that your losses never exceed your account balance, our systems monitor your margin in near real-time and will automatically close out your open positions if your account equity falls below the 100% margin requirement. While our 100% margin requirement and near real-time margin system is designed to limit your trading losses and help ensure that total losses never exceed your total account balance, you do risk incurring losses greater than your account balance, especially during periods of extreme market volatility. While it is not FOREX.com’s policy to hold clients responsible for modest negative balances, we do reserve the right to hold clients responsible for large debit balances and when special circumstances apply. For this reason, we strongly encourage you to manage your use of leverage carefully. Increasing leverage increases risk.
Forex margin is a good faith deposit that a trader puts up as collateral to initiate a trade. Essentially, it is the minimum amount that a trader needs in the trading account to open a new position. This is usually communicated as a percentage of the notional value (trade size) of the forex trade. The difference between the deposit and the full value of the trade is “borrowed” from the broker.
If your free margin drops to zero, your broker will send you a margin call in order to protect the used margin on your account. Always monitor your free margin to prevent margin calls from happening, and calculate the potential losses of your trades (depending on their stop-loss levels) to determine their impact on your free margin. With some experience, you’ll find it significantly easier to follow your margin ratio and understand the meaning of margin in Forex trading.
Now, let’s say you open a trade worth $50,000 with the same trading account size and leverage ratio. Your required margin for this trade would be $500 (1% of your position size), and your free margin would now also amount to $500. In other words, you could withstand a negative price fluctuation of $500 until your free margin falls to zero and causes a margin call. Your position size of $50,000 could only fall to $49,500 – this would be the largest loss your trading account could withstand.
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.

Not all securities can be bought on margin. Buying on margin is a double-edged sword that can translate into bigger gains or bigger losses. In volatile markets, investors who borrowed from their brokers may need to provide additional cash if the price of a stock drops too much for those who bought on margin or rallies too much for those who shorted a stock. In such cases, brokers are also allowed to liquidate a position, even without informing the investor. Real-time position monitoring is a crucial tool when buying on margin or shorting a stock.
There are benefits to be had of planning your Forex trading well in advance. In fact most experienced traders will allocate a little time on Saturday or Sunday putting together their weekday trading schedule. In this article we take a look at how the benefits of putting together your own unique trading schedule to ensure you know just when, why and what Forex you will be trading in the week ahead.
Successful FX trading is based on knowledge, proficiency and skill. It involves analytical thinking, and something visual. When looking at what are Forex robots, it is clear that they cannot properly work in this manner. Market conditions tend to change all the time, and only an experienced Forex trader can distinguish between when to enter the market, or when to stay away.
Systems that derive risk-based margin requirements deliver adequate assessments of the risk for complex derivative portfolios under small/moderate move scenarios. Such systems are less comprehensive when considering large moves in the price of the underlying stock or future. We have enhanced the basic exchange margin models with algorithms that consider the portfolio impact of larger moves up 30% (or even higher for extremely volatile stocks). This 'Extreme Margin Model' may increase the margin requirement for portfolios with net short options positions, and is particularly sensitive to short positions in far out-of-the-money options.

Let’s cover this with an example. If you have $1,000 in your trading account and use a leverage of 1:100 you could theoretically open a position size of $100,000. However, by doing so, your entire trading account would be allocated as the required margin for the trade, and even a single price tick against you would lead to a margin call. There would be no free margin to withstand any negative price fluctuation.
Margins are a hotly debated topic. Some traders argue that too much margin is very dangerous, however it all depends on trading style and the amount of trading experience one has. If you are going to trade on a margin account, it is important that you know what your broker's policies are on margin accounts, and that you fully understand and are comfortable with the risks involved. Be careful to avoid a Forex margin call.
In addition, I've had some comments from people suggesting that they'd like to see more varied order types than the simple Market Order. For carrying out proper HFT strategies against OANDA we are going to need to use Limit Orders. This will probably require a reworking of how the system currently executes trades, but it will allow a much bigger universe of trading strategies to be carried out.
