Paste the first MetaEditor error, keep the EA context attached, then move into the MQL5 compiler-fixer page if the pattern needs explanation.
EA operations resources
Practical MT4/MT5 guides for builders fixing real EA blockers.
A focused content library for CTrade setup, CopyBuffer, invalid stops, compiler errors, no-trades-in-tester, prop-style risk controls, and backtest readiness. 38 guides across five clusters link back to the Workfusionapp desk so visitors can move from learning to testing.

Intent
High
Choose the free workflow
Route the guide reader into the right desk action.
These are the three highest-intent resource handoffs: compiler repair, MT5 draft generation, and prop-style risk review. Each starts with a free workflow before pricing.
Start MT5 EA generator
Turn an MT5 brief into a reviewable EA draft before checkout. Use this when the blocker is structure, risk inputs, or missing MQL5 lifecycle.
Start prop risk checker
Review drawdown, spread, sizing, target distance, and readiness before manual testing or a prop-style account decision.
Diagnostic tool directory
Send search visitors to the matching blocker page.
These owned links keep high-intent SEO pages reachable from the resource hub before any external distribution or paid traffic is considered.

Active support pattern
CTrade setup is the fastest blocker lane right now.
The current support-to-content loop shows repeated CTrade setup questions. Start with the guide, then send only the smallest reproducible bundle if the same compiler blocker is still active.
First MetaEditor error line
Include section and CTrade declaration
Failing trade.Buy, trade.Sell, or PositionClose call
Any ResultRetcode or GetLastError output
Optional CTrade workflow review
Open the free guide and desk first. Opt in only if CTrade setup is blocking your MT5 EA and you want a focused workflow follow-up.
Intent locked: Paste compiler errors
Lead activation handoff
No email wait is required. After saving the opt-in, continue into the free desk with the same blocker so the visitor-to-lead-to-workflow path is measurable.

Next prop readiness test
Route prop-risk readers into a concrete readiness pass.
The current conversion report shows support signal for prop-style readiness, but no measured handoff from the checklist yet. This lane sends resource-hub traffic into the risk desk with source tags before any opt-in or pricing step.

Problem-first library
Start with the blocker a real builder would search.
The hub should behave like an EA triage desk: pick the symptom, read the narrow fix, then open the free console with the same intent.
CTrade
Missing include, missing trade object, wrong call shape.

CopyBuffer
Indicator handle, copied count, array access, and runtime guards.
Open fix path
Invalid stops
Broker stop distance, normalized prices, and SL/TP placement.
Open fix path
No trades
Tester setup, filters, sessions, spread, and entry conditions.
