Strategy Feasibility Review
A written review of your trading rules before anyone starts coding. We point out unclear rules, platform limits, missing conditions, and whether the idea looks buildable.

Why GreyStyle
Rules come first
We start by turning subjective trading ideas into exact conditions a computer can follow.
More than entry signals
Projects can include risk, sessions, partial closes, break-even, trailing stops, daily limits, logging, dashboards, and broker-specific behavior.
Testing that matters
We can dig into trades, historical tests, logs, session differences, and execution problems.
Clear scope before coding
Unclear rules get sorted out before a large build starts.
Built for live use
We account for terminal behavior, broker time, symbols, VPS setup, spread, slippage, and live trading realities.
GreyStyle does not claim to eliminate all bugs or guarantee identical backtest and live performance.

Example project types
These are the kinds of projects GreyStyle builds. Screenshots and private client details stay private on purpose.
Screenshot placeholder
Session strategy turned into software
- What was going wrong
- The trader had a session strategy that worked differently depending on when they entered by hand.
- What they needed
- The software needed exact trading hours, entry filters, fixed risk rules, and a clear way to close or manage trades at the end of the session.
- What made it tricky
- The tricky part was matching broker time correctly and deciding what should happen around session gaps and unusual setups.
- What we built
- We built an MT5 EA that only trades during the chosen hours, follows the agreed risk rules, and records what it is doing in the logs.
- How we checked it
- We checked the entry and exit rules in historical tests, compared results by session, and ran it on a demo account before live use.

Daily risk limits that actually stick
- What was going wrong
- The trader already knew their risk rules, but applying them by hand slipped from day to day.
- What they needed
- They needed position sizing, a daily loss limit, and an optional daily profit stop that the software would enforce.
- What made it tricky
- The hard part was counting open risk correctly, including floating P&L and accounts that aren’t denominated in USD.
- What we built
- We added trade-management rules that block new entries when the daily limit is hit and keep watching open risk while trades are live.
- How we checked it
- We walked through days where the limit should trip, days where entries should be blocked, and what happens when a new trading day starts.
Screenshot placeholder
Partial closes, break-even, and trailing
- What was going wrong
- The trade-management plan made sense on paper, but it was hard to follow the same way every time by hand.
- What they needed
- The software needed scaled exits, break-even moves, and a trailing stop after the agreed conditions hit.
- What made it tricky
- The tricky part was running those stages in order without one order change fighting another.
- What we built
- We built management logic that knows which stage the trade is in, moves cleanly to the next step, and shows that on the chart and in the logs.
- How we checked it
- We tested full trade paths — scale-outs, break-even moves, and trail activation — one stage at a time.

TradingView idea moved to MT5
- What was going wrong
- The trader had a TradingView idea and wanted it running as an MT5 Expert Advisor or indicator.
- What they needed
- They needed the same core signal logic on MT5, ready to execute, with honest notes about where the platforms disagree.
- What made it tricky
- Pine Script and MT5 don’t handle bars, alerts, time zones, or orders the same way, so a perfect match isn’t always possible.
- What we built
- We mapped the rules one by one into MT5 and wrote down the platform differences that change behavior.
- How we checked it
- We compared conditions side by side on sample charts, checked historical examples, and wrote setup notes for the MT5 side.

Trade log and results review
- What was going wrong
- Broker statements alone weren’t enough to review what the system actually did live.
- What they needed
- They needed closed trades captured, day-level summaries, and enough detail to review individual trades.
- What made it tricky
- The hard part was filtering the right deals, sending them securely, and showing them in a way that’s easy to read.
- What we built
- We used an MT5 export paired with a private results calendar so closed trades can be reviewed day by day.
- How we checked it
- We checked that trades came in cleanly, magic-number filtering was right, and the calendar totals matched the closed deals.
Screenshot placeholder
VPS setup that doesn’t fall over
- What was going wrong
- The bot failed when the terminal, charts, or allowlists weren’t set up completely.
- What they needed
- They needed clear install steps, chart attachment, WebRequest allowlists, and simple checks that the EA is actually running.
- What made it tricky
- Brokers, terminals, and VPS providers all set things up a little differently.
- What we built
- We put together a repeatable setup checklist with logging checks and written configuration notes.
- How we checked it
- We confirmed the EA attached to the chart, checked the init logs, and ran a basic live-path smoke test.
Frequently asked questions
Can every trading strategy be automated?+
No. If the rules depend on feel, stay vague, or need something the platform can’t do, the software won’t be reliable. A Strategy Review spells out what can and can’t be encoded cleanly.
Do I need fully written rules?+
Clear rules lead to better builds. If the idea is still vague, start with the $199 Strategy Review so unclear conditions get sorted before a big project starts.
Can you fix an EA built by another developer?+
Yes, when we can see the source and you can describe the expected behavior. Scope depends on code quality, missing docs, and how much of the original logic needs redesign.
Can you convert Pine Script to MT5?+
Yes. We account for differences in data, execution, brokers, time zones, and platform limits. Exact matching isn’t always possible, and we’ll document the differences that matter.
Do you guarantee profitability?+
No. GreyStyle Trading does not guarantee profits, returns, funded-account approval, strategy performance, or identical results between backtesting and live trading.
Will my strategy remain confidential?+
Project details stay private and aren’t shared publicly without permission. Formal confidentiality terms can be discussed before work starts.
What files and information should I provide?+
Send entry and exit rules, risk rules, session and time-zone needs, screenshots or examples, platform details, and any existing source code. The clearer the docs, the clearer the quote.
Do you offer ongoing maintenance?+
Maintenance and later changes can be quoted separately unless they’re already in the original quote.
Can you install the software on my VPS?+
Yes. VPS help can include terminal setup, EA install, chart setup, basic logging checks, and setup notes on a compatible environment.
What affects the final price?+
Price depends on how complex the strategy is, how clear your docs are, how many platforms you need, testing scope, revisions, and setup needs.
