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.

Borrowing money to purchase securities is known as "buying on margin". When an investor borrows money from his broker to buy a stock, he must open a margin account with his broker, sign a related agreement and abide by the broker's margin requirements. The loan in the account is collateralized by investor's securities and cash. If the value of the stock drops too much, the investor must deposit more cash in his account, or sell a portion of the stock.
The currency exchange rate is the rate at which one currency can be exchanged for another. It is always quoted in pairs like the EUR/USD (the Euro and the US Dollar). Exchange rates fluctuate based on economic factors like inflation, industrial production and geopolitical events. These factors will influence whether you buy or sell a currency pair.
In order for this Portfolio to function with the new means of generating signals and orders it is necessary to modify event.py. In particular I've added the SignalEvent component, which is now generated by the Strategy object, instead of an OrderEvent. It simply states whether to go long or short a particular "instrument", i.e. currency pair. order_type refers to whether the order is a market order or limit order. I've not yet implemented the latter, so this will remain as "market" for now:
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.
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.

The next method, add_new_position, takes the parameters necessary to add a new position to the Portfolio. Notably, it takes the add_price and the remove_price. I have not used the bid and ask prices here directly because the addition and removal prices will depend upon whether the side is "long" or "short". Hence we need to correctly specify which price is which in order to obtain a realistic backtest:

A Portfolio Margin account can provide lower margin requirements than a Margin account. However, for a portfolio with concentrated risk, the requirements under Portfolio Margin may be greater than those under Margin, as the true economic risk behind the portfolio may not be adequately accounted for under the static Reg T calculations used for Margin accounts. Customers can compare their current Reg T margin requirements for their portfolio with those current projected under Portfolio Margin rules by clicking the Try PM button from the Account Window in Trader Workstation (demo or customer account).


The primary reason the FX market exists is to facilitate the exchange of one currency into another for multinational corporations that need to continually trade currencies (i.e., for payroll, payment for goods and services from foreign vendors, and mergers and acquisitions). However, these day-to-day corporate needs comprise only approximately 20% of the market volume. Eighty percent of trades in the currency market are speculative in nature conducted by large financial institutions, multi-billion-dollar hedge funds, and individuals who want to express their opinions on the economic and geopolitical events of the day.
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.
How can you avoid this unanticipated surprise? Margin calls can be effectively avoided by carefully monitoring your account balance on a regular basis, and by using stop-loss orders on every position to minimise the risk. Another smart action to consider is to implement risk management within your trading. By managing your the potential risks effectively, you will be more aware of them, and you should also be able to anticipate them and potentially avoid them altogether.
