There are many strategies used by traders. to manage market risks while trading. These strategies are applied either during the trade or before the trade. It is important to have measures. that protect your investments because. the markets are always in constant change. There are many different factors that traders consider. when making calculations in the market. The prevailing market conditions. The prospects of the trader. and the size of investment are all important factors to consider. when making calculations. We will look at one of the most common methods of avoiding losses. and how to go about implementing it.

Using Stop Loss to Protect the Investment

Before we go into the calculations. Let us focus on what the stop loss is. and how it is used by traders to prevent losses. The stop loss is a tool. that is used in the trading markets to mark points in the market. where a trader no longer wishes to continue trading. This strategy is used extensively in the stock markets. The stop loss is a tool used by traders of all levels. In fact, it is recommended to use this tool on all trades. Including currencies or commodities such as gold and crude oil and indices.

How to Place the Stop Loss Correctly

The placement of the stop loss depends on the calculations that a trader has done. Timing is thus important and this timing is determined by mathematical projects. The ideal application of the tool is where a trader allows the market. to move for a while before implementing the strategy. Every trader has projections about the market even before venturing into it. If you feel like the market will go up, for instance. Then the placement of the stop-loss will be determined by the first few signs. that you notice in the market.

The general rule is to always place the stop loss right under the entry price bar. This is a good way to ensure that. the trade is actually going in the forecast direction. In case the market acts contrary to expectation. then the trader knows that the market is not ripe for the preferred strategy. An exit would thus prevent any losses. The market does not always go according to traders’ expectations. This is why the placement of the stop loss should not just be backed. by instinct but also mathematical data.

How to Calculate the Placement

In general, the trade is measured by cents/pips/ticks or account-dollars. Each of these gives the trader a clue of what amount of investment is at risk of loss with each particular trade. The account-dollar measure is the most direct as it shows exactly how much could be lost in actual dollar value. For both of these measures, the difference between the entry and stop loss position is equal to the risk. If the entry point is at $5.00 and the stop loss is at $5.10, then the risked amount is $0.10.

While this serves to show the figure that is at risk, it does not exactly indicate the account at risk. In order to calculate the account risk, the position size must also be put into consideration. The position size is basically the number of investments made on each trade. A position size of 1,000 shares in the stock market would, for instance, result in an account risk of $.010 x 1,000, going by the initial example.

How to Control Account Risks

Having understood the placement risk and account risk, it is important to understand how you can protect your account from a risky market. As a general rule, the amount risked in a particular trade should represent less than 2 percent of what you have in your account. It is important to calculate the account risk before you do each trade because this is the only way to get any profit out of the market.


As stated earlier, the stop loss is a valuable tool that traders should always use when trading. This tool not only guarantees traders of proper market insights, but it also protects their investments. The market does not always go according to a trader’s expectations, having a form of risk management strategy is thus a smart move.
