Retail or beginning traders often trade currency in micro lots, because one pip in a micro lot represents only a 10-cent move in the price. This makes losses easier to manage if a trade doesn't produce the intended results. In a mini lot, one pip equals $1 and that same one pip in a standard lot equals $10. Some currencies move as much as 100 pips or more in a single trading session making the potential losses to the small investor much more manageable by trading in micro or mini lots.
Free Margin – Your free margin represents your total equity minus any margin used for leveraged trades. For example, if your equity is $1,000 and your used margin is $100, your free margin would amount to $900. Following your free margin is extremely important, as it is used to withstand negative price fluctuations from your open trades and to open new leveraged trades. It’s important to understand that your free margin increases with profitable positions, but decreases with your losing positions. Once the free margin drops to zero or below, your broker will activate the so-called margin call and close all your open positions at the current market rate, in order to prevent your equity from falling below the required margin.
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.
Trading foreign exchange on margin carries a high level of risk, and may not be suitable for everyone.

Maintenance margin for commodities is the amount that you must maintain in your account to support the futures contract and represents the lowest level to which your account can drop before you must deposit additional funds. Commodities positions are marked to market daily, with your account adjusted for any profit or loss that occurs. Because the price of underlying commodities fluctuates, it is possible that the value of the commodity may decline to the point at which your account balance falls below the required maintenance margin. If this happens, brokers typically make a margin call, which means you must deposit additional funds to meet the margin requirement.

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.
