## PercentageMargin Method And The Percentage Volatility Model

The percentage margin method is a method to size your position in the market. This is a structured way to do so and is used mostly by the intraday traders. The method, as the name suggests, lets you size the positions based on the margins.

In this method, you set an amount as the margin for any particular trade. You could also increase the capital amount in case you find more opportunities. But this should not be done randomly and should be based on the profits that you are able to accumulate in your account.

If you follow the percentage margin rule then you will be getting approximately the same amount of margin on every trade that you take. But here the volatility of each position will be different and it could happen that you may be entering a risky position which will make your portfolio very risky.

Check this out to understand how to decide on which position sizing method is suited for you.

Percentagevolatility model

Thepercentagevolatility model is another popular model that is used to size the positions and it uses the volatility of the asset underlying into consideration. The volatility is the daily movement that is expected of the underlying asset.

The way to calculate volatility is to look at the difference between the high and the low for the last few days and then average it out. But one concern with this method is that it does not consider the gaps in the calculation. This is why you can use the average true range to calculate the stock volatility.

The method lets you define the volatility amount and the exposure that one can assume for a given amount of capital.

What is the percentage risk?

As a trader, you need to figure out which method of equity estimation and what position sizing works the best for your trades. Another method that is commonly used is known as the percentage risk method to size positions.

In this method, you analyze your loss yourself before you enter a trade. This is basically the stop loss that you will be placing on the trade. The percentage risk method controls the size of the position which is the function of risk and this is defined as the stop loss.

Again it does not matter which method you choose. All that is important is that you are comfortable with a particular method and that you have it in your trade plan and stick to it.
