QQE (Qualitative Quantitative Estimation) is an oscillator-style indicator that combines a moving average of RSI with an ATR-based smoothing of RSI changes to produce a smoothed signal line and a trend filter. It is implemented for cTrader and supports multi-timeframe operation, visual arrows, and email alerts. The indicator is intended for traders who use momentum/oscillator signals for entries and exits.

How it works (technical summary)

• Core components:
• • RSI calculated on price (configurable period).
  • Exponential moving average (MA) applied to RSI (FastFactor smoothing).
  • ATR-like measurement of absolute changes in the RSI MA, smoothed using Wilder’s-type smoothing and scaled by SlowFactor.
  • A smoothed “level” (TrLevelSlow) derived from the RSI MA and the ATR-of-RSI smoothing.
• Signals:
• • Buy: the RSI MA (blue) crosses the 50 level from below after having crossed above the smoothed line (yellow).
  • Sell: the RSI MA crosses the 50 level from above after having crossed below the smoothed line.
• Multi-timeframe: you can choose an upper timeframe to calculate the QQE on higher-timeframe bars while displaying results on the current chart timeframe.
• Alerts & visuals: configurable chart arrows on crossovers and level crosses; optional email alerts.

Inputs / Default parameters

• FastFactor (RSI MA smoothing): default 5
• RSI Period: default 14
• Slow Factor (ATR-of-RSI multiplier): default 4.236
• AlertOnCrossover, AlertOnLevel: booleans to enable notifications
• AlertLevel: default 50
• ArrowsOnCrossover / ArrowsOnLevel and colors for up/down icons
• EnableEmailAlerts + AlertEmailFrom / AlertEmailTo
• UpperTimeframe: optional MTF setting
• ObjectPrefix: prefix used for drawn icons

Recommended use & settings

• Timeframes: works on any timeframe; common choices are 15-min to daily depending on your trading horizon. Multi-timeframe mode works well for aligning lower-timeframe entries with higher-timeframe momentum.
• Markets: works with FX, metals, indices, crypto and stocks — any liquid market where RSI-type oscillators apply.
• Typical default starting settings: RSI Period = 14, FastFactor = 5, SlowFactor = 4.236. Adjust FastFactor for faster/slower smoothing and SlowFactor to change sensitivity to RSI volatility.
• Signals should be used with risk management and confirmation (price structure, support/resistance, trend context). Consider using the higher timeframe trend or filter before acting on lower-timeframe crossovers.

Visuals & alerts

• Drawn icons for:
• • Crossover up / down (configurable colors)
  • Level up / down at AlertLevel (default 50)
• Optional email alerts when crosses or level events occur.

Limitations & notes

• Like all indicators, QQE is a lagging/momentum-based tool; false signals occur in choppy, non-trending markets.
• Backtest and forward-test on a demo account before using with real capital.
• Ensure email alert settings are configured correctly in cTrader and your mail provider to receive emails.

Installation / usage tips

• Add the indicator to a chart, optionally set an UpperTimeframe for MTF operation.
• Enable/disable arrows and alerts to suit your workflow.
• Use the ObjectPrefix to avoid collisions with other indicators.
