PatternGrade vs TrendSpider
TrendSpider is a automated technical analysis and backtesting platform. Here is where the two differ, and what PatternGrade is built to do.
The short answer
PatternGrade is purpose-built for graded end-of-day pattern work. It reads every liquid US stock after the close, grades each detection A+, A or B, and publishes the structural rules behind every grade. TrendSpider is a broad technical platform covering charting, alerts and automation. If what you want is a ranked shortlist you can read the same way every evening, that is exactly what PatternGrade is designed to hand you.
Where PatternGrade and TrendSpider differ
| PatternGrade | TrendSpider | |
|---|---|---|
| What the tool is built around | 75 named patterns and the grade on each one. Every part of the product serves the question of which setups deserve your attention. | A broad platform: dynamic charting, automated trendline and Fibonacci detection, multi-timeframe analysis, backtesting, alerts and trade automation. |
| Ranking of results | A deterministic A+ / A / B grade on every hit, taken from the pattern's own structural rules. | Scanner results are returned as matches against the criteria you configure. |
| Performance evidence | None as a user-facing feature, and no performance figures are published. Outcomes are measured internally to decide which scanners are worth keeping. | A strategy backtesting and optimisation engine you run against rules you write yourself. |
| Coverage | Covers every liquid US stock (~4,500 names), every one of them graded after the US close. | US equities plus other asset classes such as futures, forex and crypto. |
| What you get back | A graded shortlist, each hit showing the pattern drawn on the chart with reference target and stop levels taken from its geometry. | A configurable workstation you assemble around your own charts, alerts and automations. |
Why traders choose PatternGrade
- You work after the close and want a graded shortlist rather than a workstation.
- You want detections graded against published structural rules, without building and testing each pattern yourself.
- You want a public reference page for every pattern the scanner runs.
- You do not want to pay for automation features you will not use.
PatternGrade rescans every liquid US stock after each close for 75 patterns and grades every hit on its structure. How detection and grading work, and why no performance figures are published, is set out in the methodology, and every pattern has its own reference page. A grade describes chart structure, and target and stop levels are reference levels drawn from a pattern's geometry. PatternGradedoesn't give buy or sell recommendations.
Questions people ask
Is PatternGrade a TrendSpider alternative?
For end-of-day pattern scanning, yes, and that is the job it is designed around. Every detection is graded, and the structural rules behind that grade are published. TrendSpider is a broader technical platform, so many traders take the shortlist from PatternGrade and keep whatever workstation they already like.
Does PatternGrade have backtesting?
No. PatternGrade detects and grades patterns against fixed structural rules; it does not offer a backtesting engine you can point at your own strategy, which is what TrendSpider is built around. It also publishes no hit rates or performance figures of its own — see the methodology page for why.
Which one fits an end-of-day routine?
PatternGrade, straightforwardly. The graded list is ready after every US close, so an evening review starts with a ranked shortlist instead of a blank chart and a watchlist to grind through.
Is TrendSpider's pattern recognition automated too?
Yes — automated trendline, Fibonacci and pattern detection is one of its headline features, and it covers more chart-annotation types than PatternGrade does. The difference is grading: PatternGrade ranks each detection by how closely it matches the textbook definition, and publishes the rules and thresholds behind that rank.
