Changed Your Pine Script? Check Which Version Your Alert Runs
Separate the saved Pine script, chart settings and running alert. Use a release record and three checks before connecting an updated alert to execution.
Engineering notes
Practical guides for checking trading software before you rely on it. Start with what you can observe: an EA reopening after a manual close, an alert using old settings, uncertain order state or a handoff you cannot reproduce.
Your MT5 EA Reopens a Manually Closed Trade. What Should It Do Instead?
Define what a manual exit means for an MT5 EA: partial close, paused entry, fresh signals and restart recovery. Includes a concrete repair brief and acceptance cases.
MT5 Position Sizing: Check the Cash Risk Before the Backtest
Separate intended cash risk, normalized lot size and margin acceptance. A practical MT5 sizing review with three proposed failure-path tests.
NinjaTrader Price Labels: Keep the Value That Belongs to Each Line
Keep historical line values separate from their screen coordinates. Define segment identity, label placement and reload checks before changing a NinjaTrader indicator.
Import MT4 History into Excel Without Losing the Evidence
Check MT4 history exports, duplicate trades, account currencies and charges before comparing pairs in Excel. Includes three import acceptance tests.
MT5 VPS Monitoring: A Heartbeat Is Not Command Confirmation
Separate MT5 terminal health, stale account snapshots and verified command outcomes. Define target identity, expiry and reconnect acceptance checks.
Delivery Evidence Package: How to Review a Small Script Repair
Review complete source, build versions, input fixtures and paired logs. A hypothetical duplicate-alert repair shows what handoff evidence can and cannot establish.
Write Trading Bot Acceptance Criteria Before Code
Freeze starting state, trigger, exact result and evidence before a trading bot build. Use a hypothetical acceptance matrix to separate corrections from new scope.
Before You Trust a Renko Backtest, Trace One Trade
Trace one signal, order and fill before trusting a synthetic-chart backtest. Keep signal timing, reconstructed history and execution-price assumptions separate.
Why the Same EA Can Behave Differently at Another Broker
Separate symbol rules, spread, fill policy and rejected-order behavior from strategy logic before comparing one EA across brokers.
Three Acceptance Tests Every Trading Bot Should Pass Before Handoff
Test attach behavior, one new event and refresh or reconnect recovery before accepting an EA, cBot or Pine automation handoff.
Why cTrader Cloud Can Collapse an Advanced Take-Profit Ladder
Keep partial closes, trailing activation and restart recovery explicit when a cTrader cBot manages several take-profit stages in Cloud.
An MT5 Grid EA Needs One Basket State Before It Needs More Inputs
Define one two-sided basket, one-time grid levels, basket-profit closure and restart recovery before accepting a configurable MT5 grid EA.
A Paired Buy and Sell EA Needs One Explicit Cycle State
Define exactly what happens when one leg stops, the survivor closes and the EA restarts so one paired-order cycle cannot create duplicate replacements.
A Risk Flag Is Evidence, Not a Safety Rating
Separate exposure escalation, duration outliers and equity masking into evidenced trading-strategy risk flags without claiming that an unflagged strategy is safe.
A Reversal Order Can Fail Before It Ever Reaches the Broker
Diagnose a missing NinjaTrader reversal before blaming broker latency, then protect the filled position with an explicit callback-driven state machine and three acceptance tests.
A Pine Script Save Is Not Successful Until the Target Script Is Verified
Prevent Pine Script automation from saving into the wrong TradingView editor by verifying the exact script binding before dispatch and the persisted source after save.
Imported Tick Data Is Not Native NinjaTrader Market Replay
Compare NinjaTrader Market Replay, Tick Replay and imported tick data by event semantics, Level II depth and fixed-day acceptance tests.
A Webhook Bridge Is Not Reliable Until Duplicate Alerts Are Harmless
Stop TradingView webhook duplicate orders with a persisted alert ID, explicit broker outcomes and restart-safe reconciliation. Includes three acceptance tests.
