Operational plan · summary
At week 16 of the sell signal, the week closed with a +7.7% bounce and buy volume at 78% — a clear reversal from the heavy selling of recent weeks. The technical picture is becoming more nuanced: CMF has recovered to −0.28 from the −0.45 lows of early June, momentum has bounced back to −1.8 from its −2.0 trough, and the MACD histogram — still negative at −0.14 — has narrowed from prior weeks, with the signal line drawing closer. RSI has climbed to 33.5 from the 25 low two weeks ago, remaining in depressed territory but in slow recovery. On the daily chart, a double bottom has formed in the 3.3 area with a 9% intermediate rebound: a pattern worth monitoring, as it could signal short-term exhaustion of the downside move. The decline holds directionally — weekly structure still bearish, MACD negative, price below the Ichimoku cloud — but the thrust has faded. Next week, the key watch is CMF: if it slides back toward −0.40 and sell volume reclaims control, the bearish front regroups; if the bounce holds with sustained buy volume, the case for local exhaustion gains weight. Those already in a short position hold unchanged.

IQS PhaseSetup Quality Indicator (0-100): descriptor of the asset's phase relative to its volatility norm. Toward 0 = compressed/accumulation · ~50 = ordinary · toward 100 = stretched/mature. Descriptive, not predictive.
Signal StrengthCalibrated 0-100 indicator, re-modulated weekly. For buy signals it is the probability that the weekly signal reaches the first target without hitting the Stop Loss: high value = compelling bullish scenario. For sell signals it measures the amplitude of the signal week's drop: high value = very sharp drop, which may signal exhaustion rather than continuation.
Setup qualitySetup grade at trade opening. Full open = aligned conditions · Selective open = limited constraints · Operation not advised = the model flags elevated risk at entry · Watch/Skip = not operational. The asset continues to be analysed weekly anyway.
SizingCapital allocation relative to the standard budget per position. Full = 100% · Standard = 75% · Reduced = 50% · Minimum = 25%. Modulated by Signal Strength and setup quality flags.
Rank positionOrdering by Signal Strength inside the category × state pair (US Stocks or EU-UK Stocks · Open buys or Sell signals). Helps compare the current position with the others alive in the same category.
Inversion PointWeekly structural level fixing the Stop Loss reference. For a buy signal it is below entry (giving up that level invalidates the bullish reading); for a sell signal it is above entry (a breakthrough invalidates the bearish reading).
No-Trade ZonePrice band between resistance below and support above where entry is not immediately operational. When the NTZ is active, trading is suspended inside the zone; entries become valid above the upper extreme (long) or below the lower extreme (short).
Breakeven stopOperational SL stage for active buy trades: after the first-week confirmation and price advance, the stop is moved to the entry level and trade risk is zeroed out. The structural Stop Loss remains as a long-term reference.
6/8/10-week windowsThree statistical active-management moments on stock buy trades, derived from our backtest. At weeks 6, 8 and 10 trimming 10%, 20% and 30% of the position is suggested; the residual capital (the remaining 40%, untrimmed) can be kept and left to run until the inversion, with a trailing stop on the Inversion Point. Suggestions, not automatic system events.
Statistical TPs / Time exitThe TPs are statistical time+value targets: they estimate where price would be at a given week if the trade ran at average speed (ATR), and decay toward entry at the gate. The real price at the target week can be much higher (strong trend) or never reach them (weak trend). Time exit is the actual gain (entry→close of the gate week): it is why we manage by time — trimming the planned share at the set week often captures a far larger margin than the mathematical TP.
Reinforced tradeQualification of the buy trade when the confirmation week candle closes higher than the signal week. The system recognises the setup as confirmed by the price reaction.
Structural alertsPrice conditions the system considers relevant for setup qualification. Examples: above weekly EMA200 (stock far from a structural bearish framework, making a new short less safe); range trapped (stock trapped in a prolonged horizontal range).
Entry triggerType of event that operationally opens the position: breakout = breach of a key level (7-session high for a long, 7-session low for a short); pullback = pullback to the pivot or 20-day moving average after a first move in the signal direction.
Distance from highsPercentage distance from the all-time high (ATH) and frequency of tests on highs over the last 10 weeks. Close to ATH means limited running room; wide distance means room before the first significant ceiling.
Support & ResistanceThe technical levels above (resistances) and below (supports) price: moving averages, Bollinger bands, Ichimoku cloud (Kumo), historical highs and lows. Each level shows recent tests — how many times over the last ~5 months price reached it and was rejected (grazed, clean touch or decisive rejection) or broke through it (breakout/breakdown), with the date of the latest episode. More rejections = a more solid wall; a recent breakthrough = the wall has fallen.
IQS Slope (3 weeks)The direction of the IQS Phase over the last three weeks: whether the setup's tension is rising, falling or staying flat. It helps tell whether the asset is approaching a stretched/mature phase or unwinding, beyond the point-in-time IQS value.
Trade start dateThe week the current signal opened. Together with the percentage gain since start, it shows how long the trade has been running and where it sits along the management path (scale-out windows, breakeven stop).
