Overview

DCA with automatic take-profit exit when target price is reached.

Facts

•swap: use uniswap-v3-swap recipe for each buy and the final sell
•price oracle: query pool price via slot0() or use off-chain price feed (e.g., Chainlink, CoinGecko)
•target_price: user-configured take-profit threshold (e.g., bought ETH at avg $2500, sell at $3000)
•exit mode: full position sell via exactInputSingle when target_price reached

Typical Flows

DCA phase — same as `dca-order-executor`:

1.Configure: {token_in, token_out, total_amount, num_orders, interval, target_price}
2.Execute split buy orders at each interval
3.Track: {total_spent, total_acquired, avg_price}

Limit exit phase — 1 price check per interval + 2 tx on trigger:

4.At each interval, fetch current market price
5.If current_price >= target_price:

- approve(router, total_acquired) on acquired token

- exactInputSingle({tokenIn: acquired, tokenOut: quote, ...}) — sell entire position

6.Log: {exit_price, total_pnl, num_orders_executed}

Policy Controls

•Price feed reliability: Use multiple sources; stale or manipulated price data can trigger premature exit.
•Slippage on exit: Full position sell may cause significant price impact; consider splitting exit for large positions.
•Target may never be reached: DCA continues until num_orders exhausted; unreached target leaves position open.
•Gas cost on exit: Exit trade incurs additional gas; factor into P&L calculation.
•Policy denial: Exit sell must also fit within per-tx and rolling_24h limits; large positions may require split exits.
•Partial DCA completion: If target is reached before all orders execute, remaining orders should be cancelled.
•Not applicable for: single one-time swaps — use uniswap-v3-swap directly; testnet chains — underlying swap recipe targets mainnet deployments
•Partial reference: use web search for unlisted tokens, contracts, parameters, or up-to-date addresses
