What this skill does


# HTX Open Interest Tracker

Focused skill for **open interest (OI)** on HTX USDT-M perpetuals. Public endpoints — agent may call them freely.

## When to use this skill

Load this skill when the user asks about:

- "BTC perpetual OI right now"
- "How much has ETH OI changed in the last 24h?"
- "Show me OI trend for SOL-USDT"
- "Is OI surging on any contract?"
- "OI vs price divergence on BTC"
- "Total OI across all USDT-M perpetuals"

For combined OI + funding + multi-signal scoring, prefer `htx-derivatives-analyst` *(planned Layer 2)*.

## Underlying tool

Drives `htx-cli`. Binary on `$PATH` or `$HTX_CLI_BIN`. Always pass `--json`.

## Endpoint catalog (2)

| # | Method | Endpoint | CLI invocation | Description |
|---|--------|----------|----------------|-------------|
| 1 | GET | `/linear-swap-api/v1/swap_open_interest` | `htx-cli futures call GET /linear-swap-api/v1/swap_open_interest [--query contract_code=<code>] --json` | Current OI snapshot. Without `contract_code`, returns all contracts. |
| 2 | GET | `/linear-swap-ex/market/his_open_interest` | `htx-cli futures call GET /linear-swap-ex/market/his_open_interest --query contract_code=<code>&period=<period>&size=<N> --json` | Historical OI time series for trend / surge analysis. |

## Contract code format

USDT-M perpetual codes follow `<BASE>-USDT` (e.g. `BTC-USDT`).

## Period & size for historical OI

`his_open_interest` accepts:
- `period`: `60min`, `4hour`, `12hour`, `1day`
- `size`: 1 to 200

## Typical queries → CLI

| User question | CLI command |
|---------------|-------------|
| "BTC current OI" | `htx-cli futures call GET /linear-swap-api/v1/swap_open_interest --query contract_code=BTC-USDT --json` |
| "All-contract OI snapshot" | `htx-cli futures call GET /linear-swap-api/v1/swap_open_interest --json` |
| "ETH OI 4h trend last 200 bars" | `htx-cli futures call GET /linear-swap-ex/market/his_open_interest --query contract_code=ETH-USDT&period=4hour&size=200 --json` |
| "BTC OI 24h change %" | Pull 1d period size=2, compute `(latest - previous) / previous * 100` client-side |

## Output guidance

Return:
- **Current OI** in contracts (`amount`) and base currency (`volume` × multiplier)
- **24h Δ %** (compute from `his_open_interest` series)
- **Trend label**: surging (>10% in 4h), rising, stable, declining, plunging (<-10% in 4h)
- For all-contracts query: top 5 by absolute OI and top 5 by 24h growth

## OI signal interpretation

| Pattern | Signal |
|---------|--------|
| OI ↑ + price ↑ | New longs entering — bullish continuation |
| OI ↑ + price ↓ | New shorts entering — bearish continuation |
| OI ↓ + price ↑ | Shorts covering — squeeze risk |
| OI ↓ + price ↓ | Longs unwinding — capitulation |

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
