There are several indicators that help FX traders and traders of many other securities, to identify what are referred to as “oversold”, or “overbought” conditions. The most popular indicators for pinpointing the two extremes of market behaviour, are the RSI and the stochastic oscillator. The stochastic indicator is often referred to as “stochastics”, a reference based on the use of two lines to determine the reading value.
Both the RSI and stochastic indicators have a range of measurement
of 0-100 and when placed on charts and various time frames, have areas on the
charts which, when the indicator passes into, judgements are made regarding the
security being considered oversold, or overbought. For the RSI the areas are
considered to be 70 or 30; if the indicator generates a reading above 70 the
security is considered overbought, below 30 and the security is considered
oversold.
The indicator was originally developed by J. Welles Wilder Jr. and
introduced in his 1978 book; New Concepts in Technical Trading Systems. The
current popularity of the RSI indicates the popularity of technical trading
indicators, before the birth of internet trading. The standard setting of the
RSI is 14, representing a value measured over a fourteen day trading period.
Analysts and mathematicians such as Welles Wilder, created the indicator to be
used on: daily, weekly or monthly charts, although theoretically the arithmetic
supporting the indicator’s use isn’t corrupted, when used on lower time frames.
However, many technical analysts will suggest the setting shouldn’t
be altered from its standard 14 setting as doing so, whilst also placing it on
lower time frames, can generate false readings and cause traders to engage in
curve fitting behaviour; whereby they attempt to match the indicator’s movement
to prevailing conditions.
The key addition traders and analysts are encouraged to make with
regards to the RSI, is to consider including an extra level of 50 onto the time
frame. The suggestion is that this extra level of demarcation can be used as a
trading prompt to enter trades. The inference is that on approaching and
passing the 50 line, in either direction, the security is beginning to develop
trending characteristics. For example; if price moves in a bullish manner, to
cause the indicator line to pass through the 50 level in an upswing, traders
might choose to go long once 50 is reached and then stay in the trade until a reading
of 70 is reached, at which time the trade is exited.
Other strategies might involve selling or buying, when the oversold
or overbought readings are reached. For example, immediately the 70 reading is
reached, traders might short the security. However, this strategy can involve
staying in the trade for some time whilst requiring a considerably wider stop,
as the extreme, overbought conditions might remain in place, for some time.
Many traders consider combining using the oscillating qualities of
the RSI, with other indicators. A combination of the RSI + the MACD momentum
indicator, is a long standing popular choice. The MACD measures the
relationship between two EMAs, whilst the RSI measures price change in relation
to recent price highs and lows. The indicators use different formulas for the
calculations and deliver different signals, during certain trading conditions.
Traders will often look for the indicators to align, in order to deliver extra
confirmation, before they’ll commit to make a trading decision.
In the following example, only the RSI is being used and isolated on
a daily time frame, with the setting left as standard at 14. The illustration
is used as an example of how the indicator can be used to potentially identify:
oversold, overbought and trending conditions. During the month of May 2019,
GBP/USD has displayed the text book characteristics outlined in the
aforementioned description, clearly illustrating the efficiency of the
indicator, when used for the purpose the original creator intended.
It must be noted that the underlining movement in GBP/USD during the
month, is primarily related to the issues surrounding Brexit. However,
analysing the movement of the security from a technical basis only, using price
action also, clearly reveals the potential benefits of using the RSI on a
technical analysis basis singularly. Traders should also be mindful of the fact
that nearly all indicators repaint; the readings you’ll observe at any given
time, don’t necessarily correspond with the hindsight readings you’d
experience, at all the dates and times referenced.
The RSI rose above the 50 level on April 30th, as the bullish price
action developed, resulting in the 200 DMA being breached to the upside. The
RSI remained above the 50 level, without breaching the 70 line, indicating
overbought conditions. On May 8th the reading fell below the 50 level. As a
doji candle formed on the previous day, text book bearish price action
developed over a series of trading sessions, as a significant sell off ensued,
whilst the 200 DMA was breached to the downside.
This sell off continued until May 17th, as price caused the the RSI
to fall beneath the 30 level. A significant amount of circa 300 pips, could
have been theoretically banked during May 8th to May 17th, by simply following
the basic recommendations offered up by many analysts, who testify as to the
benefits of using the RSI in technical analysis. And whilst every situation is
not as ‘text book’ as the following GPB/USD trade, this example has not been
cherry picked. It’s topical, recent and the settings have not been altered, in
order to curve fit the current situation.
