After intervention, the market cannot be easily seen by USDJPY alone
Today’s market saw a strong yen-strength reaction centered on USDJPY, following moves believed to be yen-buying by the government and currency authorities.
However, what becomes important after intervention is not just the sharp drop of USDJPY. Check what distortions remain across the entire JPY cross, such as EURJPY, GBPJPY, AUDJPY, NZDJPY, CHFJPY, XAUJPY, etc.
Intervention Aftershocks PRO SCANNERisvisualizing distortions and potential reversion between currencies in a multi-timeframe from a tri-currency parity perspective.
SCANNER is one of the main features of Intervention Aftershocks PRO
Intervention Aftershocks PRO SCANNERis a dashboard that lists multiple three-currency pairs to understand which currency pairs and which timeframes show distortions. The market overview like this article is also an example of analysis using the SCANNER screen's bottom「AI MARKET REPORT PROMPT」「AI MARKET REPORT PROMPT」function.
How to read the heatmap
In SCANNER, you can confirm “which timeframe, which direction, and how strong the consensus is” from the display of each cell.
Notable points in this SCANNER
In this heatmap, focusing on JPY-related triads, A/B evaluations stand out on M15〜H1. On the other hand, D1 is almost NG, and it is not yet a stage to declare a major daily trend reversal.
Right after a significant move suspected to be intervention, price often experiences a brief pullback or adjustment after moving strongly in one direction. Therefore, rather than jumping on the initial price movement, it is prudent to check whether the A evaluation on M15 continues to exist on M30/H1, or disappears and reappears again.
With SCANNER, by confirming continuation of A/B evaluation, a shift from MR to SHIFT, and fixation of the ★Dominant leg, it becomes easier to track which pairs retain post-intervention aftershocks.
From here on, monitoring for the following changes will help organize short-term watchlists.
In this screen, the following triads stand out notably. This is not a buy/sell recommendation but a整理 to narrow monitoring targets.
Right after intervention-like moves, it is important to observe distortions not only in USDJPY’s price range but across the entire JPY cross.Look at the distortions remaining across the JPY cross.
In this SCANNER, A/B evaluations for JPY-related triads are prominent from M15 to H1,and there is a possibility that short-term to half-day aftershocks remain.
On the other hand, since D1 is NG-centered, rather than a daily trend judgment,it is natural to treat it first as a 12–24 hour short-to-mid-term observation.
Visualize currency distortions with Intervention Aftershocks PRO
Intervention Aftershocks PRO is an MT5 indicator that focuses on tri-currency parity analysis to confirm distortions between currencies after intervention or sudden changes.
SCANNER lists multiple triads and multiple timeframes, making it easy to identify where distortions remain and which timeframes are drawing more attention.
In intervention markets, a short-term price move can attract attention, but what matters is how the subsequent pullback, re-adjustment, and spillover to cross-Yen are perceived.Intervention Aftershocks PRO SCANNERis a tool to organize such “distortions remaining after price moves” on one screen and to consider which pairs to monitor next.
