Buy/Sell Signal Indicators Tested: Fractal Arrows, ZigZag, EMA Arrows and RSI+Stochastic on 16,926 Bars (2026)

Buy/sell signal indicators all draw the same thing, an arrow under a candle, and they all come from one of four calculations underneath. Instead of listing product names, I rebuilt those four logics and measured them on the same EURUSD M5 data, June 3 to August 26, 2026, taking each arrow only when a live trader could have seen it. What a signal indicator is and how the arrow gets there is covered in buy sell signal indicator explained; this page is what the arrows are worth.

What do the four arrow types score when taken live?

All four sit inside a one pip band around zero, which is the range a coin flip plus noise produces. A typical spread kills every one of them; what your broker actually charges, and why it matters more than the arrow, is in spread and swap costs on MT4. The EMA arrow is the same signal as the fast crossover pairs that lost in the moving average crossover test, only drawn as a triangle instead of two lines.

Why does the same arrow look brilliant in history?

Because two of the four logics erase arrows after they are drawn. The ZigZag waits for price to move a threshold before it commits to a swing point, and until then it keeps moving the arrow. Your history chart shows only the arrows that survived.

Scored as drawn in history, the 15-pip ZigZag arrow wins 88.2% at +10.42 pips per trade. Scored when it actually appeared, 46.7% and +0.08. A 41.5 point gap produced by nothing but timing. Fractal arrows arrive 2.8 pips after the bar they are drawn on and show a smaller version of the same split: 56.9% in hindsight, 44.5% live. The non-repainting EMA arrow scored 44.4% both ways, because there is nothing to shift; that identical pair of numbers is the practical repaint test, and non-repaint arrow indicators shows how to run it on any indicator in a few minutes.

Does confirmation from two oscillators help?

It changes the trade count, not the quality. The RSI plus Stochastic confluence arrow fired 372 times and scored 43.8%, in the same band as the others. Across 1,997 individual signals in a separate run, the two oscillators agreed on the same bar only 149 times, and where one was silent the other traded alone, per Stochastic vs RSI. What did move the Stochastic was a trend filter: a 200-period moving average took its average from -0.23 to +0.92 pips in the Stochastic overbought test. A filter on direction helps; a second oscillator mostly buys silence.

Is there any arrow that made money?

One, and only when held far longer than any arrow product suggests.

The slowest arrow on the longest hold was the only one with a clear edge, and 79 trades is enough to trust the sign but not the decimals. At 30 minutes, the hold arrow products are built for, every row was negative. The pattern matches the price-action equivalents: a 3-bar reversal or a swing marked by a market structure oscillator pays when you give the reversal room, not when you scalp it.

How should you use a buy/sell indicator, then?

As a marker of where a reversal might be, never as a trigger by itself. Take only arrows in the direction of a slow trend gate, hold them for hours rather than minutes, trade the hours that move, which on EURUSD are 8 to 11 am New York per the best hours to trade EURUSD, and before anything else run the repaint test. My DeMARK trend line is the tool I give away because its line scores the same in history as it did live, which none of the ZigZag arrows can say.

FAQ

What is the most accurate buy sell signal indicator?

Measured live, none of the four logics cleared 47% on a two hour hold. The 25-pip ZigZag reversal reached 55.7% on a four hour hold across 79 trades. Any claim of 70 to 90% accuracy is a history chart with the erased arrows missing.

How can I tell if my arrow indicator repaints?

Open the indicator on a live chart, screenshot the last 50 arrows, come back a day later and compare. If arrows moved or vanished, it repaints. A non-repainting arrow scores the same win rate in history and live.

Do non-repainting arrows make money?

Not automatically. The EMA 5/20 arrow never repaints and still lost 0.31 pips per trade before spread. Non-repainting is the minimum requirement for a test to be honest, not a source of edge.

What data did you use?

EURUSD M5, 16,926 bars, June 3 to August 26, 2026, from a live MetaTrader terminal. Each arrow was scored when it first appeared and again where it sat in final history, at 30-minute to 4-hour holds, with no stop or target.
