In advanced programming and IT systems, designing a stable communication protocol is essential. In a previous update, code adjustments were made to stabilize interactions between the mouse indicator and Chart Trade systems. A critical flaw required moving certain code lines to ensure proper response to user actions.

When planning a message protocol, converting numeric values to strings ensures clarity, prioritized over efficiency. Fixed-length arrays simplify indexing but waste memory if fields are underutilized. Alternatively, variable-length arrays avoid wasted space but add complexity and potential data loss when limits are exceeded.

In protocol design, variable-length blocks offer flexibility, but delimiters must be used for accurate data separation. The approach chosen combines alphanumeric strings with delimiters, allowing clarity and indexi...

Candlestick patterns, rooted in 18th-century Japanese trading, offer insights into market psychology via price actions like open, high, low, and close. Patterns such as Three Black Crows or Doji provide signals on supply and demand dynamics, aiding in detecting reversals or continuations. Historically, these were robust in less efficient, low-liquidity markets due to the reliance on human decision-making. A project aimed to identify these patterns, graphically marking bullish with a green line and bearish with a red one. It utilized self-written code since previous libraries couldn't be adapted for indicators. This allowed a thorough reevaluation of detection functions. In the current landscape, institutional players couple candlestick patterns with complex strategies to gauge market sentiment, using machine learning and quantitative analyses. Despite...

A CopyTrader bot is implemented with a focus on reliability and effective signal management. Initialization occurs via OnInit(), setting up an SQLite database, "CopyTrader.sqlite", with crucial tables like 'signals' for active signals and 'signals_history' for past data.

During the initial check function, all open trades are evaluated against a specified MAGIC_NUMBER. New qualifying positions trigger a "NEW" signal recording in the database while populating control arrays. The OnTradeTransaction() callback meticulously monitors any SL/TP (Stop-Loss/Take-Profit) adjustments. A detected modification prompts sending a "MODIFY" signal to the database.

When new positions are registered, the function checks if it's a buy or sell action, records the position, and stores relevant details. Closure of any trade leads to a "CLOSE" signal in the bank, and archived a...

Dive into the essential metrics for evaluating trading strategies: the Sharpe and Sortino ratios. The Sharpe ratio, developed by Nobel laureate William F. Sharpe, offers a robust measure to compare investment portfolios by calculating returns over risk using basic financial metrics. It’s ideal for gauging performance but hinges on the normally distributed return assumption. The Sortino ratio refines this by focusing on downside risk, giving a clearer picture of strategic performance without penalizing positive volatility. These tools, adaptable across various timeframes and assets, empower traders and developers to make informed decisions by accurately assessing risk versus reward in trading environments.
