We now need to determine how much we want to risk per trade given that we are going to trade 1 lot based on our example above.

The example in the image above is calculated as follows Margin = (100,000 ÷ 10) * 1.1427 = 11,427 in US dollars. In this case Margin = (Lot Size ÷ Leverage) * FX. When the currency pair is quoted in terms of US dollar, there is an additional calculation required to bring the margin requirement into terms of US dollar, and that is the exchange rate (FX). An example, where leverage is 1:10, lot size = 1, then Margin = 100,000 ÷ 10 = 10,000 in US dollars. To calculate margin needed given the leverage is a simple calculation even when the currency pair is quoted in foreign currency terms as in the case of USDJPY then Margin = Lot Size ÷ Leverage. ![]() Adding the three results together gives a total margin size of $34,449 to trade these 3 currency pairs, 1 lot each, with a leverage of 10 to 1. Repeating the process for another two currency pairs, for example, GBPUSD and USDJPY would give margin requirements of $13,022 and $10,000 respectively. The difference comes from the lot units being quoted in Euros, which are worth more than $1. The number that some traders would come up with in their heads would be $10,000. ![]() This amount is larger than what would initially come to mind based on a 10:1 leverage. When you click on calculate for the above data, you get a margin requirement of $11,427.00. Then the next item is leverage, in this case, 1:10, followed by account currency, USD, and lot size, 1. Let’s say one of the FX pairs you are going to trade is the EURUSD, which is the first item at the top of the picture. The picture below shows a screenshot of the margin calculator. But always keep in mind, that you should only invest with money that you can afford to lose.įor example, if you want to trade at least 3 different FX pairs at 1 lot per pair, using a leverage of 10 to 1, how much margin would you need? There is a handy forex margin calculator tool available at XM.com which allows you to calculate margin needed to trade a given FX pair, leverage and lot size. These considerations go beyond the scope of this article, and will be a personal matter for each trader to decide on. Forex Margin Calculatorīefore you start trading, you need to decide on the amount of funds you will finance your account with. There are various websites that offer these calculators for free that you can use once you become familiar with them. In this article, we will review an extensive set of spot forex trading calculators Margin Calculator, Stop loss Calculator, Lot Size Calculator, Profit/Loss Calculator, and Pip Value Calculator. In addition, it is important to keep in mind that currency pairs can have different pip values, based on whether the FX pair is quoted in terms of US dollars, or whether the FX pair is quoted in terms of a non-USD foreign currency. We need to look at the potential profit and loss of the trade where the target price is and where the stop loss is, in relation to our entry point. This approximation is also used for this Moody diagram calculator.Download the short printable PDF version summarizing the key points of this lesson…. This approximation is valid for flow regimes where Reynold's number is between 4,000 and 5*10 8, and pipes with a k/D ratio less than 0.01. Moody's approximation or otherwise known as Moody equation is given as: f = 0.0055 ( 1 + (2 * 10 4 * k/D + 10 6/Re) 1/3) This calculator utilizes Moody's approximation to determine the Darcy friction factor. One of the commonly used approximation is given by Lewis Moody, otherwise known as Moody chart or Moody diagram. The Colebrook-White equation can only be solved using numerical approximations. Where Re is the Reynold's number for the fluid flow. ![]() The term f, or friction factor, can be estimated for a pipe having surface roughness k using the Colebrook equation: 1/√f = -2 * log(k / (3.7 * D) + 2.51/(Re * √f)), Where g is the acceleration due to gravity. The friction head loss is used in the Darcy-Weisbach equation to estimate the pressure drop Δp for a fluid flowing at a velocity V, in a pipe having length L and diameter D, and friction factor f, such that: Δp = f * L * V 2 / (2 * g * D), In addition to this, changes in pipe cross-section like enlargement or contraction, bends, and branching contributes to minor losses. The major causes of these losses include surface roughness and friction. The loss in energy of fluids while travelling through a pipe or ducts causes reduction in pressure and velocity which is known as head loss.
