What the AFI Stochastic Indicator does on the chart
The AFI Stochastic indicator plots a Stochastic oscillator (%K and %D) in a separate window with 20/50/80 reference levels, measuring where the close sits inside the recent high-low range.
It alerts only when %K crosses %D near the oversold or overbought zone, filtering out the mid-range crosses that are usually noise.

How to read signals from the AFI Stochastic Indicator
Also, the signal is the %K/%D cross near an extreme.
Entry idea (long). %K crosses above %D below 20.
Entry idea (short). %K crosses below %D above 80.
Exit idea. Exit at the opposite extreme.
Tuning the AFI Stochastic Indicator inputs
Start with the defaults, then tune for your market. In practice, KPeriod (default 14) sets the averaging length — raise it for smoother, slower signals or lower it for faster, more sensitive ones; DPeriod (default 3) sets the averaging length — raise it for smoother, slower signals or lower it for faster, more sensitive ones; Slowing (default 3) sets the averaging length — raise it for smoother, slower signals or lower it for faster, more sensitive ones. Every alert channel — pop-up, sound, email and mobile push — toggles independently in the same inputs panel, and alerts fire once per closed bar.
Recommended timeframes and instruments
AFI Stochastic Indicator is a momentum tool, so match the timeframe to your holding period.
- M15 to H1 for intraday momentum entries.
- H4 to Daily for swing signals and divergence.
On M1 to M5 the readings turn faster and noisier, so confirm with price structure. Also, common pairs are EURUSD, GBPUSD, AUDUSD and XAUUSD.
How to install on MT4 and MT5
Installation is the same for every indicator on this site. Also, still, unzip the download, copy the compiled .ex4 into your MT4 MQL4/Indicators folder (or the .ex5 into MT5 MQL5/Indicators), refresh the Navigator, then drag it onto the chart. For the full step-by-step with alert setup and troubleshooting, see our guide to installing MT4 and MT5 indicators.
Best practices and tips
- Do not fade momentum in a strong trend; overbought can stay overbought.
- Favour signals that align with the higher-timeframe direction, and watch for divergence against structure.
- Wait for the bar to close before acting on a signal.
- Backtest your configuration on at least 200 closed bars before trading live.
- Keep position sizing small while you learn how the tool behaves on your instrument.
- Review your results weekly and prune settings that underperform.

FAQ
What does the AFI Stochastic measure?
It plots a clear signal layer that the AFI Stochastic computes from recent price and volume on the chart.
Is it non-repaint?
By default the indicator only confirms a signal on the bar close, so the printed signal locks in once that bar closes. Also, still, hence, some users prefer the early intra-bar mode for faster signals — both options are in the inputs.
Which timeframe should I use?
There is no single best timeframe. Next, m15 to H1 is a common starting point for intraday traders, and H4 to D1 works for swing traders. Backtest the configuration on the timeframe you actually trade.
Does it work on instruments other than forex?
It works on any instrument MT4 and MT5 supports — forex majors, gold (XAUUSD), indices like US30 and NAS100, and major cryptos. Then, fast-moving instruments may need a smaller period setting.
Can I add alerts?
Yes. In addition, pop-up, sound, push, and email alerts live in the inputs panel. On MT4 and MT5 the alert plays on the bar close that triggers the signal. Thus, yet, the indicator ships with full alert functionality built in: popup alerts on the chart, push notifications to mobile MetaTrader, email alerts, and a sound alert with a configurable .wav file. you toggle each channel independently from the inputs panel (EnableAlerts, EnablePopup, EnablePushNotify, EnableEmail, EnableSound). Alerts trigger once per closed bar.
For external background reading, see the technical indicator basics. Are results guaranteed?
