Invented by and named after renowned educator Alan H. Andrews, the technical indicator known as Andrew's Pitchfork can be used by traders to establish profitable opportunities and swing possibilities in the currency markets. On a longer-term basis, it can be used to identify and gauge overall cycles that affect the underlying spot activity. Below, we'll explain this indicator and how you can apply it to your trades using two approaches: trading within the lines and trading outside the lines.
Defining Andrew's Pitchfork
Andrew's pitchfork (sometimes referred to as "median line studies") is available on numerous programs and charting packages and widely recognized by both novice and experienced traders. Comparable to the run-of-the-mill support and resistance lines, the application offers two formidable support/resistance lines with a middle line that can serve as support/resistance or as a pseudo-regression line. Andrews believed that market price action would gravitate toward the median line 80% of the time, with wild fluctuations or changes in sentiment accounting for the remaining 20%. As a result, the overall longer-term trend will (in theory) remain intact, regardless of the smaller fluctuations.
If sentiment changes and supply and demand forces shift, prices will stray, creating a new trend. It is these situations that can create significant profit opportunities in the currency markets. A trader can increase the accuracy of these trades by using Andrew's pitchfork in combination with other technical indicators, which we'll discuss below.
Applying Andrew's Pitchfork
In order to apply Andrew's pitchfork, the trader must first identify a high or low that has previously occurred on the chart. The first point, or pivot, will be drawn at this peak or trough and labeled as point A (as shown in Figure 1). (For further reading on pivots in forex trading, see "Using Pivot Points In Forex Trading.")
Once the pivot has been chosen, the trader must identify both a peak and a trough to the right of the first pivot. This will most likely be a correction in the opposite direction of the previous move higher or lower. In Figure 1, the minor correction off of the trough (point A) will serve us well as we establish both points B and C.
Once these points have been isolated, the application can be placed. The handle of the formation begins with the pivot point (point A) and serves as the median line. The two prongs, formed by the following peak and trough pair (points B and C), serve as the support and resistance of the trend.
Figure 1: Application of Andrew's pitchfork to a chart showing the price action of the EUR/USD. The pivot point (A) has been drawn at a previously occurring trough, and points B and C have been established to the right of the pivot. The line drawn from point A is the median line, while the two "prongs" serve as support and resistance.
When the pitchfork is applied, the trader can either trade within the channel or isolate breakouts to the upside or downside of the channel. In Figure 2, you can see that the price action works well serving as support and resistance where traders can enter off of bottoms (point E) and sell from tops (point D) as the price will gravitate towards the median. As always, the accuracy of the trade improves when confirmation is sought. A basic price oscillator will be just enough to add to the overall trade.

Additionally, the trader can initiate positions on breaks of the support and resistance. Two examples are presented at points F and G. Here, the market sentiment shifted, creating price action that strayed from the median line and broke through the channel trendlines. As the price action attempts to fall back into the median area, the trader can capture the windfall. However, as with any trade, sound money management and confirmation must play important roles in execution.
Trading Within Andrew's Pitchfork Lines
Let's take a look at how a trader might profit from trading within the lines. Figure 3 is a good example, as it shows us that the price action in the EUR/CAD currency pair has bounced off of the median line and has risen to the top resistance of the pitchfork (point A1). Zooming in a little closer in Figure 4, we see a textbook evening star formation. Here, the once-rising buying momentum has started to disappear, forming the doji, or cross-like, formation right below the upper prong. When we apply a stochastic oscillator, we see a cross below the signal line, which confirms downside momentum.
The trader would do well to place the entry at point X (Figure 4), slightly below the close of the third candle when taking these indications into consideration. The entry would be executed on the downward momentum as the price action once again gravitates towards the median line, in practice with sound money management (and including an appropriate stop loss). Even better, the trader could make close to 1000 pips over the life of the trade.
Figure 3: Another great setup in the EUR/CAD cross currency. Here we see a prime example of an "inside the line" profit opportunity as price action approaches the 1.5000 figure.
Figure 4: A closer look at the opportunity reveals textbook technical formations that aid the entry. Here, the trader can confirm the trade with the downward crossover in the stochastic and the evening star formation.
Trading Outside Andrew's Pitchfork Lines
Although trading outside the lines occurs less frequently than within, they can lead to extended runs of profit. However, they can be trickier to attempt. The assumption here is that the price action will gravitate back towards the median, similar to wayward price action within the lines. However, it is possible that the market has decided to shift its direction; therefore, the break outside may be a new trend forming. To avoid a catastrophic loss, simple parameters are added and placed in order to capture the retracements into the channel and, at the same time, filter out adverse movements that ultimately result in traders closing their positions too early.
Looking at Figure 5, we see that the price action at point A offers such an opportunity. The chart shows that the EUR/USD price action has broken through support in the first week of April. Once the break has been identified, we isolate and zoom in to obtain a better perspective.
Figure 5: Notice how the price action gravitates once again towards the median. This is a great opportunity, but money management and strategy remain important in capturing the run-up.
In Figure 6, the trader is offered multiple opportunities to trade back into the overall trend as the underlying spot consolidates in ranging conditions. However, the real opportunity lies in the break that occurs in October. The trader can see that the price action ranges or consolidates prior to the break, establishing the $1.1958 support level (shown as the blue line).
Using a moving average convergence divergence (MACD) price oscillator, the individual sees that a bullish convergence signal is forming, as there is a large peak and a subsequently smaller secondary peak in the histogram. The entry is key here. The trader will see a potential breakout opportunity as the price rises to test the upper resistance at $1.2446.
Figure 6: The convergence in the MACD, combined with the decline in the underlying spot price, suggests a near-term upward break
In order to place the entry in this example, first you need to make sure that the upper resistance is tested. If the resistance is not tested, it may mean that a downward trend is in the works, and you will have saved yourself the trouble of entering into a non-profitable trade. You can see in Figure 6 that the price action breaks back into the prongs in early October, hitting a high of $1.2446.
If the price action can break above this resistance, it will confirm a further rise in the price action, as fresh buying momentum will have entered the market. As a result, you should place your entry 30 pips above the target (shown as the red line), with your subsequent stop applied upon entry. Once your order is executed, the stop should be applied five pips below the previous session low. The assumption is that the low will not be tested because the price action will continue to rise and not spike downward due to the buying momentum.
Breaking Andrew's Pitchfork Down Step-by-Step
Although the two methods discussed here (trading within the lines and trading outside the lines) may seem complex, they are easily applied when you break them down step-by-step. Traders will find that the pitchfork method yields far better results when applied to major currency pairs such as the EUR/USD and GBP/USD because of their nature to trend rather than range. Cross currencies, although they do exhibit trending patterns, tend to be choppier and yield less satisfying results.

Figure 7: Identifying two great opportunities in the NZD/USD currency pair.
Now, let's break the process down. The NZD/USD currency pair, seen in Figures 7, 8 and 9, presents a perfect example of both "within the lines" and "outside the lines" opportunities. First we'll take the in-line approach, choosing example A in Figure 7:
- Identify price action that has broken through the median line and that is approaching the upper resistance prong.
- Testing the upper resistance prong, recognize a textbook evening star or another bearish candlestick pattern. For example, in Figure 8, we see a textbook evening star formation at point X. This will serve as the first signal.
- Confirm the decline through a price oscillator. In Figure 8, a downward cross occurs in the stochastic oscillator, confirming the following downtrend in the currency. Also, notice how the cross occurs before the formation is complete, giving traders a heads up.
- Place the entry slightly below the close of the third and final candle of the formation. As little as five pips below the low will usually suffice in these situations.
- Apply a stop to the position that is approximately 50 pips above the entry. If the price action rises after the evening star, traders will want to exit as soon as possible to minimize losses, but still maintain a healthy risk measure. In this example, the entry would ideally be placed at 0.6595, with a stop at 0.6645 and a target of 0.6454 – an almost 3:1 risk/reward ratio.
Figure 8: An evening star formation at point X suggests an impending sell-off that is confirmed by the downward crossover in the stochastic oscillator.
For breaks outside the trendlines, we take a look at the next example, point B in Figure 7. Here, the price action has broken above the upper trendline, but looks set to retrace back to the median or middle line. Let's take another approach, using the same NZD/USD currency pair:
- Identify the price action moving toward the median or middle line. Traders want to confirm that the price is indeed falling and will break back through the upper trendline. In Figure 9, the currency spot falls through the trendline, confirming selling pressure.
- Identify the significant support/resistance line. Here, traders will want a confirmed break of a significant support level in order to isolate sufficient momentum and increase the probability of a successful trade.
- Place the entry order 30 pips below the support level. In our example (see Figure 9), the support level is at the 0.7200 figure, meaning that the entry would be placed at 0.7180. The following stop would be applied slightly above the 0.7300 figure – the previous session's high – and give us an almost 2:1 risk/reward ratio when we take profits at the 0.7000 price.
- Receive confirmation through a price oscillator. The downward cross that occurs when the stochastic oscillator is used gives traders ample confirmation of the break of support in the price.
Figure 9: Taking a closer look, we can see a great opportunity as the price action moves towards the median line.
The Bottom Line
Andrew's pitchfork can provide currency traders with profitable opportunities in the longer- or intermediate-term, capitalizing on preferably longer market swings, although it's worth noting that it is more often applied in the futures and equities forums than in the currency markets.
When the pitchfork is applied accurately and is used in combination with strict money management and textbook technical analysis, a trader is able to isolate great setups while weeding out the choppier price action in the forex markets. The trade will be able to ride its way to profitability compared to its shorter-term peers, given that traders apply all of the criteria we outlined above.
