SOL Ranking Sniper v1.0.0

欢迎使用 SOL 涨幅榜狙击策略！

我们实时监控 OKX DEX 涨幅榜，当新币进入榜单时自动触发买入，跌出榜单时自动卖出。策略内置 25 项安全检查（流动性、持仓集中度、Dev 钱包等）+ 动量评分（0-125分），只交易评分达标的高质量标的，6 层退出机制全程保护仓位。

投资案例：

小陈用 2 SOL 启动涨幅榜狙击。某天上午一个新币 $BONK2 冲进涨幅榜前 10，动量评分 98 分，安全检查全过。
机器人以均价 $0.0012 自动买入，持仓期间 $BONK2 继续拉升 40%。
跌出榜单触发排名退出，以 $0.00165 自动卖出，单笔盈利约 $82（+37.5%）。
同日另一个币安全检查未通过（Dev 钱包集中度过高），自动跳过，规避了一次归零风险。

Automated Solana token sniper that monitors the OKX DEX trending ranking, applies a 3-layer safety filter with momentum scoring, and executes trades with a 6-layer exit system. Available as standalone strategy-ranking-sniper binary.

Pre-flight Checks

Run immediately when this skill is triggered — before any response or command. Always follow these steps in order. Do not echo routine command output to the user; only provide a brief status update when installing, updating, or handling a failure.

Step 1: Check onchainos

which onchainos

• Found → run onchainos --version to confirm, then proceed to Step 2.
• Not found → install automatically:
  bash curl -sSL https://raw.githubusercontent.com/okx/onchainos-skills/main/install.sh | sh
• If install succeeds → verify with onchainos --version, then proceed to Step 2.
• If install fails → notify the user to install manually:
  自动安装失败，请手动安装 onchainos： https://github.com/okx/onchainos-skills
  Stop here until user confirms onchainos is available.

Step 2: Check skills-store

which skills-store

• Not found → install:
  bash curl -sSL https://raw.githubusercontent.com/purong-huang-1121/skills-store/main/install.sh | sh

• Check for updates: Read ~/.cargo/bin/.skills-store/last_check_ranking_sniper and compare with current timestamp:
  bash cached_ts=$(cat ~/.cargo/bin/.skills-store/last_check_ranking_sniper 2>/dev/null || true) now=$(date +%s)

• If cached_ts is non-empty and (now - cached_ts) < 43200 (12 hours), skip the update.
• Otherwise, run the installer to check for updates.

Step 3: Check strategy-ranking-sniper

which strategy-ranking-sniper

• Found → proceed.
• Not found → install:
  bash curl -sSL https://raw.githubusercontent.com/purong-huang-1121/skills-store/main/install_strategy.sh | sh -s -- strategy-ranking-sniper
• If install succeeds → verify with strategy-ranking-sniper --version, then proceed.
• If install fails → notify the user:
  自动安装失败，请手动安装 strategy-ranking-sniper： curl -sSL https://raw.githubusercontent.com/purong-huang-1121/skills-store/main/install_strategy.sh | sh -s -- strategy-ranking-sniper
  Stop here until user confirms installation.

+---------------------------------------------------------------------------+

Authentication

Requires two sets of credentials:

OKX API (for ranking data + swap execution):

OKX_API_KEY=...
OKX_SECRET_KEY=...
OKX_PASSPHRASE=...

Solana Wallet (for on-chain signing and swap):

SOL_ADDRESS=...          # Solana wallet public address
SOL_PRIVATE_KEY=...      # Solana wallet private key (base58, 32 or 64 bytes)

Optional:

TELEGRAM_BOT_TOKEN=...   # Telegram bot token for trade/error notifications
TELEGRAM_CHAT_ID=...     # Telegram chat ID for alerts

Telegram credentials can also be set in the config file (~/.skills-store/ranking_sniper_config.json).

Before Starting the Bot

IMPORTANT: Before running strategy-ranking-sniper start, you MUST:

1. Run strategy-ranking-sniper config to show the user their current parameters
2. Present the parameters in a readable table and ask if they want to adjust any
3. If the user wants to change parameters, edit the config file at ~/.skills-store/ranking_sniper_config.json directly
4. Parameters are persisted across restarts

Example flow:

# Show current config
strategy-ranking-sniper config

# Start with custom budget and per-trade amount
strategy-ranking-sniper start --budget 1.0 --per-trade 0.1

# Or start in dry-run mode first to observe
strategy-ranking-sniper start --budget 0.5 --per-trade 0.05 --dry-run

Core Strategy

What It Does

1. Every 10 seconds, fetches the top N Solana tokens by 5-minute price change from OKX DEX ranking
2. For existing positions: checks 6-layer exit system (ranking exit, stops, trailing, TP)
3. For new tokens entering the ranking: applies 3-layer safety filter (25 total checks)
4. Calculates momentum score (0-125) — only buys if score >= threshold
5. Executes swap via OKX DEX aggregator with Solana on-chain signing
6. Sends Telegram notifications on buy/sell/error events

What It Won't Do

Rule	Reason
No tokens already seen	known_tokens set prevents re-entry
No tokens in cooldown	Post-sell cooldown (default 30min)
No buying above max positions	Default 5 simultaneous positions
No buying below budget	Budget tracking prevents over-deployment
No buying with low score	Momentum score must meet threshold
No buying with high risk	3-layer safety filter rejects unsafe tokens
No trading after daily loss limit	Auto-stops at configured % loss
No trading after circuit breaker	5 consecutive errors triggers 1h cooldown

State includes:
- known_tokens — Set of all token addresses ever seen (prevents re-entry)
- positions — Map of token_address -> Position (with buy price, time, peak PnL, trailing state)
- trades — Trade history (last 100 entries)
- stats — Cumulative stats (buys, sells, invested, returned, daily PnL)
- errors — Consecutive error tracking for circuit breaker
- last_sell_times — Per-token cooldown timestamps

Key Concepts

• Ranking-based entry: Unlike signal-based scanners, this bot only considers tokens that appear in the OKX top-N trending list. Entry is triggered by a token being new to the ranking AND passing all safety checks.
• Ranking-based exit: The primary exit signal is a token dropping off the ranking entirely. This is Layer 1 of the exit system and takes priority over most other exit conditions.
• Momentum Score: A composite score (0-125) combining buy pressure, price change, trader count, liquidity, and bonus signals (smart money, low concentration, etc.). Prevents buying tokens that pass safety but lack momentum.
• Known tokens set: Once a token is seen in the ranking, it enters the known_tokens set permanently (within a session). The bot will never re-enter the same token. Use reset --force to clear.
• Gradient take-profit: Sells in 3 tranches (25%/35%/40%) at increasing profit levels, rather than all-at-once. Locks in partial profit while allowing further upside.
• Trailing stop: Activates when PnL reaches a threshold (default +8%), then sells if price drops by the drawdown percentage (default 12%) from the peak.
• Dry-run mode: Executes the full pipeline (ranking fetch, safety checks, scoring) but skips actual swap execution. Actions are logged as DRY_RUN. Useful for validating filter parameters.

Edge Cases

Scenario	Behavior
No ranking data available	Saves state, outputs no_ranking_data
Circuit breaker tripped (5 errors)	Rejects all ticks for cooldown period (default 1h)
Daily loss limit exceeded	Bot stops, requires reset --force to restart
Bot previously stopped by limit	Rejects ticks with reason, requires reset
Budget exhausted	Skips all new buys, continues monitoring exits
Max positions reached	Skips new buys, continues monitoring exits
Token already in known_tokens	Skipped silently (no re-entry)
Sell fails (insufficient liquidity)	sell-all retries with halved amounts (up to 4x)
Advanced-info API fails	Token skipped with reason
Price fetch fails	Position exit check skipped for that token
SOL_ADDRESS not set	Error on tick/start/sell commands
SOL_PRIVATE_KEY not set	Error on swap execution (buy/sell)
Bot already running	start rejects with existing PID warning
No running bot	stop returns error
Reset without --force	Returns error, requires confirmation
wSOL ATA missing	Auto-created and funded before buy swap
Blockhash expired	Fresh blockhash fetched from Solana RPC
Solana RPC broadcast fails	Falls back to OKX broadcast endpoint
Transaction not confirmed	Polled for up to 60 seconds before failing

Troubleshooting

Symptom	Cause	Fix
"SOL_ADDRESS not set"	Missing env var	Set SOL_ADDRESS to your Solana wallet address
"SOL_PRIVATE_KEY not set"	Missing env var	Set SOL_PRIVATE_KEY (base58, 32 or 64 bytes)
Circuit breaker trips	Repeated API/swap failures	Check logs at ~/.skills-store/ranking_sniper.log, fix root cause, wait 1h or reset
No buys happening	Score threshold too high, or safety filters too strict	Try --dry-run to see skip reasons, adjust config thresholds
All tokens skipped by slot_guard	Thresholds set to production values	For testing, lower min_change_pct, min_liquidity, min_holders, etc.
Sell fails repeatedly	Low liquidity token	Use sell-all (auto-retries with halved amounts) or manual sell
"Bot stopped" on tick	Daily loss limit or prior stop	Run ranking-sniper reset --force to clear state
High slippage on swaps	Slippage tolerance mismatch	Adjust slippage_pct in config (default 3%, raise to 5-10% for low-liquidity memes)
Telegram not working	Missing or incorrect bot token/chat ID	Set in config file or env vars, verify with Telegram BotFather

Security Notes

• Private key: Loaded from SOL_PRIVATE_KEY env var, used only for transaction signing, never logged
• API auth: HMAC-SHA256 via OKX ApiClient, keys only in HTTP headers
• Atomic state writes: Write to .tmp file then rename to prevent corruption
• Fail-closed: API failures result in skipping the token, not proceeding with partial data
• Capital controls: Budget tracking, position limits, daily loss limits, and circuit breaker prevent runaway losses
