Sindex AIWhat is the Stochastic Overbought?
When the slow stochastic reads above 80, price has been closing near the top of its 14-candle range. That is normal in a strong rally, so the actionable event is when %K falls back below 80: the most recent closes have slipped away from the highs, and the buying pressure that carried price to the top of the range is cooling.
This makes it a favourite for short-term mean-reversion traders in crypto, where pumps are steep and reversals can be equally steep. Shorting the exit from overbought rather than the entry into it avoids fighting a rally that is still accelerating.
How the Stochastic Overbought works
The scanner uses a slow stochastic with a 14-period lookback and 3-period smoothing for both %K and %D. The short condition is met when %K closes at or below 80 on the latest bar after closing above 80 on the previous bar. It is a strict crossover; a symbol drifting in the 70s does not qualify.
Scoring starts at 50 and adds two points for each point by which the previous %K reading exceeded 75. Signals that fall from readings in the high 90s therefore rank above those that barely poked above 80 before turning down.
With a 25-candle minimum the strategy is available on 15m through 1d. Short-timeframe signals mark intraday exhaustion and are frequent; 4h, 12h and daily signals are sparser and more often coincide with swing highs.
Rules
Entry rules
- Enter only after the bar where %K closes at or below 80.
- Look for %K to have crossed below %D as well, confirming the turn.
- Price should be at resistance, a prior high, or stretched well above a moving average.
- A bearish candle pattern on the signal bar, such as a shooting star, strengthens the case.
- Short on the close of the signal bar or on a retest of the high that fails.
Exit rules
- Stop above the high of the rally that carried the stochastic above 80.
- Cover as %K approaches 20 or at the nearest support, whichever comes first.
- The setup fails if %K climbs back above 80 and price makes a new high.
- If price consolidates just below the high while %K drifts sideways, cut the trade rather than wait for a breakdown.
Best conditions
- In a downtrend or range on the higher timeframe, where overbought readings mark rally highs.
- When bearish divergence is present: a higher price high with a lower stochastic high.
- After a low-volume push to the highs, which often lacks follow-through.
- On 1h to 4h charts where the pullback has room to develop.
Pitfalls
- In strong uptrends the stochastic can stay above 80 for many bars; the first dip below is often just a pause.
- Lower timeframes produce a constant stream of overbought exits, most of which are noise.
- Shorting an altcoin that is being rotated into by the broader market can be very costly.
- Risk reminder: overbought does not mean about to fall; hard stops and small size are essential for fades.
Stochastic Overbought FAQ
- Which stochastic level triggers the Sindex short signal?
- The scanner looks for slow stochastic %K, using 14,3,3 settings, to close at or below 80 after being above 80 on the previous bar. That marks the exit from overbought territory.
- Is a stochastic above 80 a sell signal?
- Not on its own. It shows price closing near recent highs, which is what strong trends do. The strategy waits for %K to leave the zone and works best with resistance and divergence.
- Can I build this fade into an automated strategy?
- Yes, Algo Forge lets you combine the stochastic condition with price or volume filters and backtest the result before running it.
