When new traders come into the Foreign Exchange Market, they often look for a simple to indicator to use. Some like to turn to moving averages to identify trends, whereas others like to see when markets are hot and cold with the use of an oscillator. One of the most popular oscillator’s is the RSI.
The Purpose of Oscillators like RSI
The Relative Strength Index (RSI) is probably the most commonly known and used technical oscillator as it can identify when a market is “overbought” or “oversold” as told by the oscillator’s extreme ranges. As an oscillator, RSI is plotted with values between 0 and 100. The value of 70-100 is considered overbought and a reversal to the downside is likely whereas the value of 30-0 is considered oversold and a reversal to the upside is to be expected in a range.

The rules above work best in a range bound market like USDJPY during the early half of 2014, the RSI extremes worked well for the “buy low, sell high crowd”.
Looking at the chart above, you’d be in line to think that the RSI looks like an ideal tool for FX Traders. To some degree, the RSI is a great tool but to see the RSI only as a buy low, sell high tool can be difficult when markets break out when the tradition rules are applied however, a game plan that is too simplistic can do more harm than good. Too simplistic means that the traditional measure of “buy when below 30 or breaking above 30” and “sell when above 70 or breaking below 70.”
When Traders Have a Hard Time Trading With RSI
Sometimes, markets break out into a strong trend. In fact, according to Elliott Wave, the first breakout is usually just the beginning of multiple moves higher with the potential of an extended leg of the uptrend. As you can imagine, if the market has broken out higher, then a selling an overbought market is very dangerous. This is especially true if you do not manage your risk on a trade.

A new trader who has learned about RSI would likely be very frustrated after the last year of price action on the USDOLLAR index. The prior 7 months before the chart shows consistent overbought readings while USDOLLAR traded up for all of 2013 until July 2013 when in turned south harshly. If you recognized the downtrend and then waited for a break above 70 to sell USDOLLAR, you never got the opportunity until 13 months later when USDOLLAR flashed an overbought signal and has since gone parabolic.
How to Use RSI in Extended Moves
When you find a strong trend unfolding, it’s best to adjust how you use RSI. A helpful way to adjust your use of RSI is to change what you define as oversold and overbought. In a strong uptrend, oversold may be as little as 40-50 range and in a strong downtrend, overbought and therefore an opportunity to sell or load into a trade may be as low as 50-60 before the downtrend resumes.

The highlighted circles show signals to sell based on lowering your overbought qualification. When you’ve done this, you can place your stop a few ATR above your entry or the prior swing high if less than that level. The examples shown above are on daily charts but you can use this adjusted range to increase your RSI effectiveness in strong trends on intraday charts as well.
