In the world of MetaTrader 5 development, efficiently managing graphical objects on trading charts is crucial. This article presents an advanced approach to track changes in graphical objects using event-driven logic. By leveraging the `OnChartEvent()` handler, developers can monitor critical events such as creation, modification, and deletion of graphical objects. This method reduces resource consumption by avoiding constant synchronous checks, though it's restricted to live charts.

The solution introduces arrays to store previous object properties, enabling seamless comparison and detection of changes. While this initial test version sets the foundation, future iterations aim to encompass all open charts, enhancing the functionality and responsiveness of trading applications.

The Range Vector Fibo Logic Indicator is an advanced tool for traders using the "One Candle" and "Daily Breakout" strategies, commonly utilized by institutional traders. Its primary function is to automate key analytical processes such as projecting breakout levels, stop loss zones, and Fibonacci profit targets based on the previous day's volatility.

The tool is particularly beneficial for trading the Daily High/Low Breakout strategy by identifying precise entry points and target levels. Black lines indicate breakout triggers, signaling potential entries when a candle closes beyond these levels. Stop loss levels, depicted by red dotted lines, are set at a 0.9 Fibonacci retracement, warning of setup invalidation if reached. The blue solid lines, representing take profit zones, extend to the 1.25 Fibonacci expansion, marking the day's volatility limit.

Efficient tick data storage and processing have been significantly enhanced through advanced compression methods. By compressing tick data up to 3.5 times more effectively than traditional .tcs files, storage requirements are substantially minimized. Key improvements include encoding price variations, often between -8 and 7 points, with just 4 bits, allowing Ask and Bid to be packed into a single byte.

For further optimization, a byte can denote the time difference, with values exceeding typical limits encoded across more bytes. Additional ZIP compression can reduce data size by up to 50%. Notably, compression to three bytes is possible when price shifts range from -129 to 128, incorporating two bytes for prices and one for time.

Data for BTCUSDT demonstrate average tick sizes reduced to 1.498 bytes post-compression. With zip reduction, substanti...
