Four Types of Stops

 

1. Equity Stop

This is the simplest of all stops. The trader risks only a predetermined amount of his or her account on a single trade. A common metric is to risk 2% of the account on any given trade. On a hypothetical $10,000 trading account, a trader could risk $200, or about 200 points, on one mini lot (10,000 units) of EUR/USD, or only 20 points on a standard 100,000-unit lot. Aggressive traders may consider using 5% equity stops, but note that this amount is generally considered to be the upper limit of prudent money management because 10 consecutive wrong trades would draw down the account by 50%.

One strong criticism of the equity stop is that it places an arbitrary exit point on a trader's position. The trade is liquidated not as a result of a logical response to the price action of the marketplace, but rather to satisfy the trader's internal risk controls. 

 

2. Chart Stop

Technical analysis can generate thousands of possible stops, driven by the price action of the charts or by various technical indicator signals. Technically oriented traders like to combine these exit points with standard equity stop rules to formulate charts stops. A classic example of a chart stop is the swing high/low point. In Figure 2 a trader with our hypothetical $10,000 account using the chart stop could sell one mini lot risking 150 points, or about 1.5% of the account.

 

3. Volatility Stop

A more sophisticated version of the chart stop uses volatility instead of price action to set risk parameters. The idea is that in a high volatility environment, when prices traverse wide ranges, the trader needs to adapt to the present conditions and allow the position more room for risk to avoid being stopped out by intra-market noise. The opposite holds true for a low volatility environment, in which risk parameters would need to be compressed.

One easy way to measure volatility is through the use of Bollinger bands, which employ standard deviation to measure variance in price. Figures 3 and 4 show a high volatility and a low volatility stop with Bollinger bands. In Figure 3 the volatility stop also allows the trader to use a scale-in approach to achieve a better "blended" price and a faster breakeven point. Note that the total risk exposure of the position should not exceed 2% of the account; therefore, it is critical that the trader use smaller lots to properly size his or her cumulative risk in the trade.

 

4. Margin Stop

This is perhaps the most unorthodox of all money management strategies, but it can be an effective method in FX, if used judiciously. Unlike exchange-based markets, FX markets operate 24 hours a day. Therefore, FX dealers can liquidate their customer positions almost as soon as they trigger a margin call. For this reason, FX customers are rarely in danger of generating a negative balance in their account, since computers automatically close out all positions.

This money management strategy requires the trader to subdivide his or her capital into 10 equal parts. In our original $10,000 example, the trader would open the account with an FX dealer but only wire $1,000 instead of $10,000, leaving the other $9,000 in his or her bank account. Most FX dealers offer 100:1 leverage, so a $1,000 deposit would allow the trader to control one standard 100,000-unit lot. However, even a 1 point move against the trader would trigger a margin call (since $1,000 is the minimum that the dealer requires). So, depending on the trader's risk tolerance, he or she may choose to trade a 50,000-unit lot position, which allows him or her room for almost 100 points (on a 50,000 lot the dealer requires $500 margin, so $1,000 – 100-point loss* 50,000 lot = $500). Regardless of how much leverage the trader assumed, this controlled parsing of his or her speculative capital would prevent the trader from blowing up his or her account in just one trade and would allow him or her to take many swings at a potentially profitable set-up without the worry or care of setting manual stops. For those traders who like to practice the "have a bunch, bet a bunch" style, this approach may be quite interesting.

 

Conclusion

As you can see, money management in FX is as flexible and as varied as the market itself. The only universal rule is that all traders in this market must practice some form of it in order to succeed.
