Bollinger Squeeze Expansion
bandwidth percentile breakoutBandwidth = (upper − lower) ÷ middle. When it sits in the bottom 20th percentile of its own 120-bar history, the squeeze is on.
Rules you can check before you trade them.
Every strategy carries its exact rules, an annotated chart of the setup, the research behind why it should work at all — and the conditions under which you should not take it.

Rate of Change Threshold
momentum as a number, not as a crossingThe simplest possible measurement: price now divided by price N bars ago. If it is above a threshold, the instrument is in an uptrend; below, a downtrend. No smoothing, no crossings, no lag beyond the lookback itself.

MACD Histogram Acceleration
the popular one, and what it actually measuresThe MACD histogram is the difference between two exponential averages, minus a third average of that difference. Rising histogram is usually described as accelerating momentum.

Engulfing Bar at a Level
the most-taught candle, in the only place it means anythingA bar whose body completely covers the previous bar's body, closing in the opposite direction. Taken alone it is one of the weakest signals in retail trading — it happens constantly and predicts very little.
Evidence: ModerateIntermediate
Failed Breakout Reversal
the break that does not stickPrice breaks a level, everyone who was waiting for the break is in, and then it closes back inside. Those positions are now wrong, their stops sit just beyond the level, and the move away from it is fed by them being taken out.
Evidence: ModerateIntermediate
Compression Into a Level
when the pullbacks stop reaching backPrice approaches a level and, instead of bouncing away, each pullback from it becomes shallower. The lows step up, the level holds flat, and the space between them runs out.
Evidence: WeakBeginner
Wide-Range Bar Retracement
half of the move that started itOne bar moves a long way. Price then retraces into the middle of that bar, and the trade is taken there on the assumption that the move continues.
Evidence: WeakIntermediate
Order Block Retest
the last opposing candle before the moveThe last down candle before a strong move up is marked as a zone, and a return to it is treated as a place to buy. The reasoning offered is that institutional orders were placed there and that some of them remain unfilled.
Evidence: WeakIntermediate
Fair Value Gap Fill
the thin patch a fast move leaves behindThree consecutive candles where the first bar's high sits below the third bar's low leave a band of prices that barely traded. Price moved through it too quickly for an auction to happen.
Evidence: ModerateProfessional
Structure Break Failure
the break that turns out to be the topA structure break is supposed to confirm continuation, which is exactly what makes a failed one informative. Price takes out the last swing high, everyone treats it as confirmation, and then it closes back below.
What the evidence rating means
Strong
The mechanism has peer-reviewed, FX-specific research behind it.
Moderate
The mechanism is sound, but at least one step of it is untested.
Weak
Practitioner literature only — no published research supports the mechanism.
It rates the mechanism — whether there is published research explaining why the market should behave this way. It does not rate profit. Strong does not mean the trade will work. None of these have been run on our own account, and no page here shows a backtest figure.
What the level means
Beginner
One instrument, one timeframe, every rule visible on the chart.
Intermediate
Several conditions have to line up, and execution starts to matter.
Professional
Needs an outside data feed, a basket, real order flow, or an unusual tolerance for lumpy losses.
The level describes what it takes to run the strategy, not how well it works. Several Beginner pages are better evidenced than several Professional ones — a basket carry trade is Professional because it needs eight currencies and a swap table, not because it is cleverer than buying a pullback.

Trading carries risk and most retail accounts lose money. Nothing in this library is financial advice or a recommendation to trade. The charts are illustrations of the rules on constructed candles — they are not records of trades and not backtests.
