Stephen's Simple Scalper: Zigzag + Bollinger Bands

System overview

The Simple Scalper picks entries at statistical extremes, the moments when price has stretched well beyond its normal trading range and is likely to snap back. After extensive testing, the 30-minute chart proves the most reliable timeframe, offering enough signals without the noise of very short charts. The recommended pairs are once again EUR/USD and GBP/USD for their tight spreads, which matter greatly on a scalping system where a single winner might only be 10 to 20 pips. SSS is a hybrid reversal system: the Zigzag indicator provides the structural turning-point signal while the Bollinger Bands provide the statistical confirmation that price is overextended. Because it fights the immediate momentum by buying dips and selling spikes, it requires more nerve and tighter risk management than a trend system, and it should only ever be traded in the direction of the higher-timeframe trend, never blindly against strong momentum.

Chart setup

Open a clean 30-minute chart on EUR/USD or GBP/USD and add only two tools. First, the Zigzag indicator, found under Custom Indicators in the Navigator, set to a pale blue colour so it does not disappear among the red and green candles. Second, Bollinger Bands with a period of 20, a shift of 0, and applied to the close, coloured dark blue for clear visibility. Save the layout as a template. The most important instruction here is what not to add: do not clutter the chart with any additional indicators. SSS relies on reading price behaviour at the bands, and extra tools only create conflicting signals and analysis paralysis. A clean chart is a deliberate part of the method, not a matter of taste.

The critical Zigzag repainting warning

You must understand this before trading a single lot. The Zigzag indicator repaints, meaning it revises its own signals as new candles form. When you look at a historical chart, the Zigzag appears flawless, connecting every top and bottom perfectly, which fools many beginners into thinking they have found a holy grail. In real-time trading it behaves very differently. A Zigzag point that has just attached to a new high or low can move as the next candle develops, because the indicator is constantly recalculating where the most significant swing lies. The correct way to use it is to treat a freshly painted point as a possible signal, then wait for the candle to close and for the Bollinger Band confirmation before acting. Never enter simply because the Zigzag has drawn a line, because that line is provisional and may vanish. Anyone who claims a Zigzag-based system is perfect is looking at repainted history, not live results.

The mandatory trend filter

SSS is a counter-swing system, but it must still respect the larger trend, and skipping this filter is the fastest way to lose money with it. Before considering any entry, switch to the 4-hour chart and check the direction of the Bollinger Band centre line, which is a 20-period moving average. If that centre line is trending downward, you may only look for SHORT entries on the 30-minute chart, selling into upward spikes. If the centre line is trending upward, you may only look for LONG entries, buying downward dips. If the centre line is moving sideways and the market is clearly ranging, do not trade SSS on that pair at all; switch to a different pair with a clearer trend. This filter keeps you buying dips within an uptrend and selling rallies within a downtrend, which is far safer than trying to pick tops and bottoms in a directionless market where reversals fail repeatedly.

Entering a long position

With the 4-hour Bollinger centre line trending up, watch the 30-minute chart for the following. First, the Zigzag paints a new low, attaching to the current candle. Second, that new low candle must have its body or tail extending at least 25 percent below the lower Bollinger Band, confirming price has stretched to a statistical extreme. Third, and crucially, do not enter if the candle is a full-bodied Marubozo with no upper wick, because that shape shows strong downward momentum that is likely to continue rather than reverse. You want to see rejection, a lower wick or a small body poking below the band, which signals sellers are becoming exhausted. Enter as the candle closes. The discipline to skip clean momentum candles even when the Zigzag and band conditions are met is what separates profitable SSS traders from those who get run over catching a falling knife.

• Zigzag paints a new low on the current candle.
• Candle body or tail at least 25 percent below the lower band.
• Reject full-bodied Marubozo candles with no upper wick.
• Only when the 4-hour centre line is trending up.

Entering a short position

With the 4-hour Bollinger centre line trending down, watch the 30-minute chart for the mirror image. First, the Zigzag paints a new high. Second, that new high candle must have its body or tail extending at least 25 percent above the upper Bollinger Band, confirming an overextended spike. Third, do not enter if the candle is a full-bodied Marubozo with no lower wick, because that signals strong buying pressure likely to continue. You want to see an upper wick or rejection tail above the band, showing that buyers pushed price up but could not hold it. Enter as the candle closes. As with longs, the temptation on shorts is to sell every candle that pokes above the band, but only those showing rejection at a statistical extreme, within a downtrend, carry a genuine edge. The rest are noise.

• Zigzag paints a new high on the current candle.
• Candle body or tail at least 25 percent above the upper band.
• Reject full-bodied Marubozo candles with no lower wick.
• Only when the 4-hour centre line is trending down.

Stop loss placement

Because SSS is a scalping system, stops must be tight, typically 5 to 15 pips. Place the stop loss just beyond the wick of the entry candle: for a long, just below the candle's low; for a short, just above the candle's high. The logic is that if price pushes past the very extreme that triggered your reversal signal, the setup has failed and you want out fast with a small loss. If the required stop would be larger than roughly 15 pips, the candle is too big and the setup is not a true scalp, so skip it and wait for a cleaner one. As with every system, never move the stop further away to avoid being stopped out. On a tight scalping system, one refusal to accept a small loss can produce a loss many times larger than a normal winner, destroying the maths that makes the system work.

The split-profit exit strategy

There are two ways to exit an SSS trade. The safer option is to set your take profit equal to your stop loss distance for a clean 1:1, banking a quick, high-probability win. The recommended option is a split exit that balances consistency with upside. Close 50 percent of the position when price reaches the Bollinger Band centre line, which is the natural first target for a reversal, then move the stop loss on the remaining half to breakeven. This locks in profit on part of the trade and removes all risk from the rest, letting the remaining half run toward the opposite band if momentum continues. The psychological benefit is significant. Taking half off the table satisfies the urge to secure a win, while the risk-free runner gives you exposure to the occasional large reversal that pays for many small trades. Over a large sample, this structured exit tends to outperform closing the whole position at the first target.
