ftd-detectorDetects Follow-Through Day (FTD) signals for market bottom confirmation using William O'Neil's methodology.
Ftd Detector is an agent skill from tradermonty/claude-trading-skills. Detects Follow-Through Day (FTD) signals for market bottom confirmation using William O'Neil's methodology. Dual-index tracking (S&P 500 + NASDAQ) with state machine for rally attempt, FTD qualification, and post-FTD health monitoring. Use when user asks about market bottom signals, follow-through days, rally attempts, re-entry timing after corrections, or whether it's safe to increase equity exposure. Complementary to market-top-detector (defensive) - this skill is offensive (bottom confirmation).
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 18 other files, including scripts and reference files (for example `references/ftd_methodology.md`, `references/post_ftd_guide.md` and `scripts/fmp_client.py`).
The repository describes itself as: Claude Code skills for equity investors and traders — market analysis, technical charting, economic calendars, screeners, and trading strategy development. The licence is MIT.
3 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit eab8d5c. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Ships 12 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
FMP_API_KEYFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Ftd Detector loads about 1.3k tokens when it runs, and up to ~5k if it reads all its reference files. Until then it costs about 129 tokens; SKILL.md has 541 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Detects Follow-Through Day (FTD) signals for market bottom confirmation using William O'Neil's methodology. Ftd Detector is an agent skill from tradermonty/claude-trading-skills. Detects Follow-Through Day (FTD) signals for market bottom confirmation using William O'Neil's methodology.
Ftd Detector fits situations like: user asks about market bottom signals; follow-through days; re-entry timing after corrections; whether its safe to increase equity exposure.
Run `npx skills add tradermonty/claude-trading-skills --skill ftd-detector -a claude-code`. Or copy the skill folder (skills/ftd-detector in tradermonty/claude-trading-skills) into .claude/skills/ftd-detector in your project. Claude Code loads it when a task matches its description.
Run `npx skills add tradermonty/claude-trading-skills --skill ftd-detector -a codex`. Or copy the skill folder (skills/ftd-detector in tradermonty/claude-trading-skills) into .agents/skills/ftd-detector in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add tradermonty/claude-trading-skills --skill ftd-detector -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/ftd-detector, .gemini/skills/ftd-detector, .github/skills/ftd-detector and .opencode/skills/ftd-detector in your project.
Going by SKILL.md and its folder, Ftd Detector needs Python for the scripts in its folder, the command-line tools its instructions call (python3) and credentials named FMP_API_KEY. Our summary lists: Python 3; A credential in FMP_API_KEY.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Ftd Detector is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.3k tokens (SKILL.md is roughly 5.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 3.6k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Ftd Detector: Signal Detector (garrytan/gbrain, 31k stars), Signals Scout Anomaly Detection (PostHog/posthog, 40k stars), Signals Scout PR Follow Up (PostHog/posthog, 40k stars) and Detecting Pv Signals (maziyarpanahi/openmed, 5.5k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
