RSI goes from 0 to 100. Stochastic goes from 0 to 100. Williams %R goes from -100 to 0 — and flips everything upside down. It’s not trying to be different. The negative scale gives you a clearer view of momentum extremes, and many traders find it more intuitive once you understand the inversion.

What Is Williams %R?
Williams %R — also called the Williams Percent Range — was developed by Larry Williams. It measures where the current closing price sits within the highest high and lowest low of a lookback period (default 14). The scale runs from -100 to 0.
Here’s how to read it: Readings below -80 mean the asset is oversold — price closed near the low of the range, suggesting a bounce is coming (CALL signal). Readings above -20 mean it’s overbought — price closed near the high, suggesting a drop is coming (PUT signal). The -50 level is neutral.
The difference between Williams %R and Stochastic: Williams %R uses the highest high and lowest low of the entire period, while Stochastic uses the closing price relative to the current range. Williams %R is slightly more sensitive to price extremes — it catches tops and bottoms faster.
When to Use This Strategy
| Condition | Works | Avoid |
|---|---|---|
| Trending market | ✅ Trade with the trend at extreme levels | ❌ Ranging = %R oscillates between levels |
| Volatile pairs | ✅ Fast reaction to price extremes | ❌ Low volatility = rarely hits -80/-20 |
| London session | ✅ Best momentum for extreme readings | ❌ Asian session = weaker signals |
Step-by-Step Trading Rules
Step 1: Add Williams %R
Rule: Add Williams %R (14) to your 5-minute chart. Default period is 14. Set overbought at -20 and oversold at -80.
Setup: On Pocket Option, go to Indicators → Williams Percent Range. Set period to 14. Make sure the -20 and -80 levels are visible. The indicator will appear below your chart as a single line.
Step 2: Check the Higher Timeframe Trend
Rule: Check the 15-minute chart. If the trend is up, only take CALL signals from oversold (below -80). If the trend is down, only take PUT signals from overbought (above -20). This single filter doubles your win rate.
Step 3: Wait for the Extreme Reading
Rule: Wait for Williams %R to enter oversold (below -80) for a CALL or overbought (above -20) for a PUT. The line must pierce the level — touching it is not enough.
The key difference from RSI: Williams %R reaches extreme levels more frequently, meaning you get more signals. But this also means the signals are slightly less reliable than RSI extremes. The trade-off: more opportunities, similar win rate.
Step 4: Wait for Exit From Extreme
Rule: Don’t enter while %R is still in extreme territory. Wait for the line to exit the extreme zone. For a CALL: %R was below -80 and now crosses back above -80. For a PUT: %R was above -20 and now crosses back below -20. This exit confirms momentum is shifting.
Step 5: Set Expiry and Enter
Rule: Enter immediately when %R exits the extreme zone. For binary options: 10-15 minute expiry on a 5-minute chart. For forex: TP at 15 pips, SL at 10 pips.
Williams %R signals are fast — the move often happens within 5-10 minutes of the signal. If the price hasn’t moved in your direction within 2 candles, the signal may be weak.

Real Trade Example
Williams %R Oversold on EUR/USD (5-min chart)
EUR/USD had dropped sharply for 30 minutes. Williams %R plunged to -90 (deep oversold). The line stayed below -80 for 3 candles — price was still dropping but momentum was exhausted. On the fourth candle, %R crossed back above -80. That was our CALL signal. We entered with 15-minute expiry. Price bounced 18 pips — payout 86%.
The key signal: %R stayed oversold while price made a lower low. That’s Williams %R divergence — price making a new low but the indicator refusing to go deeper. That’s momentum exhaustion, and it’s one of the most reliable signals in the strategy.

Common Mistakes
- Confusing the scale. Williams %R goes from -100 to 0, not 0 to 100. -80 is oversold, not 80. If you’re used to RSI, double-check your readings before entering.
- Trading while %R is still in extreme. Don’t enter when %R is at -85 — wait for it to exit the zone. The exit confirms the reversal is starting.
- Ignoring the higher timeframe. A %R oversold signal is much stronger when the 15-minute trend is also up.
- Using the wrong period. Period 14 is standard. Period 7 is too sensitive. Period 21 is too slow for binary options.
- Not watching for divergence. When price makes a new low but %R doesn’t go deeper than the previous low, that’s a powerful CALL signal.
FAQ
What’s the difference between Williams %R and RSI?
Williams %R is more sensitive and reaches extreme levels more often. RSI is smoother and produces fewer but more reliable signals. Use RSI for divergence, Williams %R for quick momentum shifts.
What is the best Williams %R setting for binary options?
Default period 14 with -80/-20 levels is the sweet spot for 5-minute charts. It gives enough signals without being too noisy.
Can I use Williams %R with other indicators?
Yes. It pairs well with a 20-period SMA for trend confirmation. Above the SMA + oversold %R = strong CALL signal. Below the SMA + overbought %R = strong PUT signal.
