MQL4/MQL5 & Pine Script Developer в StratCoreAlpha
I develop MQL4/MQL5 Expert Advisors, indicators, dashboards and trade-management tools from explicit written rules. I also convert authorized TradingView/Pine Script logic to MetaTrader 5 and turn rough ideas into testable technical specifications.

Public proof
This profile includes five published MT5 products and four official open-source CodeBase diagnostics. The newest is MT5 EA Acceptance Harness (#76039): a non-trading script with eight deterministic entry-state fixtures, 0-error/0-warning compilation and an isolated 8/8 MT5 runtime pass. MT5 Cash Risk Probe (#75981) provides bounded read-only cash-risk sizing. MT5 Broker Environment Report (#75871) captures non-sensitive broker/symbol constraints; MT5 Order Preflight (#75874) checks a hypothetical order against volume, tick-size, stop-distance and filling rules. Other public work includes a multi-symbol wick scanner, risk and spread monitors, an RSI multi-timeframe dashboard and a one-click trade panel.

Services
- One reproducible MQL4/MQL5 bug fix or bounded modification
- Custom MT4/MT5 EAs from written rules
- Indicators, dashboards, alerts and trade managers
- Authorized Pine Script to MT5 conversion
- Risk sizing, daily limits, break-even, partial-close and trailing logic
- Strategy formalization and acceptance-test specifications

Process
1. Freeze platform/build, entry, exit, risk, timing and edge cases.
2. Approve a short scope with should-happen and should-not-happen examples.
3. Implement and test against that behavior.
4. Deliver editable source, compiled build, documented inputs and setup notes.

Entry pricing
- Small bug or bounded modification: 30-80 EUR
- Simple indicator or trade-management component: 70-160 EUR
- Simple custom EA or conversion: 150-300 EUR
- Multi-symbol, multi-timeframe or infrastructure work: fixed quote after specification

I do not guarantee profit, returns, drawdown or prop-firm results. I implement the approved behavior transparently, work only with legitimately owned editable source and never decompile protected EX4/EX5 files. Send the platform, source or written rules, symbol/timeframe and one positive plus one negative example for a bounded price and timeline.

Опубликовал код MT5 Cash Risk Probe - Read-Only Sizing
Read-only MT5 script that estimates stop-distance cash loss in account currency, reserves explicit cash costs and floors volume to the broker grid. It never sends or modifies an order.

Daily drawdown is not one MT5 metric. Before coding a dashboard, freeze four decisions:

1. Day boundary: broker-server date or a named timezone.
2. Reference: start-of-day balance, start-of-day equity, or intraday equity high-water.
3. P/L: realized only or realized plus current floating result.
4. Restart behavior: reconstruct the reference from deal history or persist the first valid observation and disclose the limitation.

For a high-water definition, the testable formula is DrawdownAmount = max(0, PeakEquity - CurrentEquity), and DrawdownPct = 100 * DrawdownAmount / PeakEquity with a zero guard. The peak must only move upward during the selected day and must survive chart reloads and terminal restarts.

Useful acceptance cases are more important than a pretty panel: one realized win/loss, one open position, one threshold crossing without duplicate alerts, one recovery and recross, and one restart. If two dashboards use different choices above, both can compile cleanly while reporting different numbers.

Five questions I freeze before coding any Expert Advisor

1. Signal timing: current tick, current candle, or last closed candle? Multi-timeframe rules must state which bar is final.
2. Position model: one position, pyramiding, hedging or netting? Define symbol, direction, Magic Number and manual-trade filters.
3. Risk units: fixed lots, percent risk, money, points or ATR? Define rounding, minimum volume and what happens when a stop is invalid.
4. Broker behavior: digits, stop/freeze levels, filling mode, spread limits, retry rules and trading-session boundaries.
5. Acceptance examples: provide at least one should-trade case, one should-not-trade case and the expected SL/TP calculation.

A phrase such as “enter when trend is strong” cannot be tested. A rule such as “after the H1 candle closes above EMA 50, enter on the next tick only if spread is below X points and no matching position exists” can be implemented and verified.

Freezing these details before development prevents most scope disputes and makes backtests reproducible. This same checklist works for indicators, dashboards, alerts and Pine-to-MT5 conversions.

I am opening a few fixed-scope slots for MQL4/MQL5 work: one reproducible EA or indicator bug, one bounded feature such as risk sizing, break-even, partial close or a session filter, one simple MT5 EA from explicit rules, or one Pine Script-to-MT5 conversion.

For an accurate quote, send the platform, editable source or written rules, symbol/timeframe, current versus expected behavior and chart examples.

I work specification-first and deliver source code, documented inputs and a verification checklist. I do not decompile protected files or promise trading results.

I am opening a few fixed-scope slots for small MQL4/MQL5 work:

- one reproducible EA or indicator bug
- one bounded feature such as risk sizing, break-even, partial close or a session filter
- one simple MT5 EA from explicit entry and exit rules
- one TradingView/Pine Script behavior map or MT5 conversion

The fastest way to get an accurate quote is to provide the platform, editable source or written rules, symbol/timeframe, current versus expected behavior and one or two chart examples.

I work specification-first and deliver source code, documented inputs and a verification checklist. I do not decompile protected files and do not promise profit, returns or prop-firm results.

My profile contains five published MT5 products and several public CodeBase tools that show the type of dashboards, risk controls, indicators and trade management I build.

NNFX D1 Aroon Kijun ATR EA is an automated strategy template for MetaTrader 5 that implements a rule-based daily timeframe workflow with ATR-based risk management, structured entries, and disciplined exits. The Expert Advisor is intended for end-of-day operation and processes signals only on the close of each new daily candle. The EA uses a baseline (Kijun), a confirmation signal (Aroon), and a volume/momentum filter (Jurik RSX) to determine trade direction and qualify entries. It opens two

Renko Velocity Heatmap is a separate-window indicator that converts standard time-based price series into Renko-style blocks and colors them by momentum speed. Each block represents a fixed Renko box size, while the color intensity reflects how fast the block was formed relative to recent average formation time. Slow movement appears dim/neutral, fast movement becomes more saturated, enabling quick visual assessment of acceleration and deceleration in trend moves. The indicator is designed for

Transparent Renko Overlay Indicator Overview Transparent Renko Overlay Indicator displays Renko bricks directly on the main price chart as a semi-transparent overlay. Unlike traditional Renko charts that require a separate offline window, this indicator allows traders to view standard candlestick price action and Renko structure simultaneously on the same chart. The overlay helps identify trend direction, price noise, and consolidation phases without losing time-based market context. Key
