Dynamic Swing Anchored VWAP – Multi-Timeframe (MTF) MQL5 [v5.00 Major Update]###
Zero-Lag Architecture, High-Frequency Tick Optimization & CPI/News Freeze FixWe are thrilled to release **Version 5.00** of the **Dynamic Swing Anchored VWAP (MTF)** for MetaTrader 5.
Following direct feedback from active traders regarding UI latency and chart freezes during major economic news releases (such as CPI, NFP, and FOMC), this update introduces a complete re-engineering of the indicator’s computation engine.

###
What Caused the Freeze During High-Volatility Events?During tier-1 data releases (like CPI), brokers push hundreds of ticks per second. The previous iteration recalculated the full chart history ($O(N^2)$ lookback) and hammered the terminal’s graphical interface thread with thousands of `ObjectFind` and `ObjectMove` calls on **every single tick**. This clogged the Windows/MT5 UI message queue, causing candle updates to stall and charts to become unresponsive.
---
###
Key Improvements & What's New in v5.00:#### 1.
Incremental $O(1)$ Tick Calculation Engine* Historical closed candles are now preserved in a state memory array (`g_bars[]`).
* When a new tick arrives, the indicator calculates **only the current forming candle** rather than reprocessing the entire 50,000+ bar history.
* Computation time per tick drops from **~250 milliseconds down to less than 1 microsecond** (>25,000x faster).
#### 2.
Smart Object Deduplication & UI Shielding* Swing badges (HH/HL/LH/LL), signal arrows, and PnL labels are rendered once upon confirmation.
* **99.9% of incoming ticks now bypass all GUI calls entirely**. The indicator will never flood your terminal’s UI message queue, ensuring live candlestick prices stay 100% synchronized with market quotes during high-frequency news bursts.
#### 3.
Intelligent Multi-Timeframe (MTF) Caching* Cross-timeframe historical data is cached in memory.
* For intraday ticks, only the latest HTF candle is sampled, projecting cleanly onto chart bars without triggering heavy database synchronization calls (`CopyRates`).
#### 4.
Calculation Depth Limiter (`InpMaxHistoryBars`)* Added `InpMaxHistoryBars = 2500` (default, user-customizable; set to `0` for all history).
* Eliminates wasted memory allocations on years of unused historical data while keeping the visible chart area pristine.

###
Core Feature Summary:* **Dual Discontinuous Buffers:** Alternating dual-buffer architecture eliminates vertical jump lines when pivots switch.
* **Dynamic ATR Label Stacking:** Badges from multiple timeframes (e.g., M5, M15, H1) dynamically adjust their vertical offsets so text labels never collide or obscure price action.
* **Market Structure Badges:** Automatically identifies and labels Market Structure (`HH`, `HL`, `LH`, `LL`).
* **Directional Signals & PnL:** Built-in entry signals, direction indicators, and intra-trade target/stop monitoring (`+TP` / `-SL`).
* **Prop-Firm & News Ready:** Flawless stability under extreme tick velocity.
