The assistant searched the codebase and found that all active bots were using the **28APR26** expiry (April 2026 monthly contract), which had just expired on April 28. The user then requested a rollover to the **26MAY26** expiry and a restart of both running bots.\n\n### Actions Taken\n\n1. **Identified all expiry references** across two bot systems:\n - **Claude Bot** (`/home/ubuntu/bots/Claude_bot/config.py`): profiles DLF_SMMA, INFY_SMMA, INDUSINDBK_SMMA (active) and HAL_SMMA (disabled) all used `28APR26` expiry and corresponding futures symbols like `DLF28APR26FUT`.\n - **LT 3-Candle Bot** (`/home/ubuntu/bots/three_candle_bot/lt_3candle_bot.py`): `SYMBOL_FUT = \"LT28APR26FUT\"`, `EXPIRY_DATE = \"28APR26\"`.\n - **EOD script** (`lt_3candle_eod.py`): `SYMBOL_HIST = \"LT28APR26FUT\"`.\n\n2. **Stopped both bot services** (`claude_bot.service` and `lt_3candle_bot.service`) using `sudo systemctl stop`.\n\n3. **Updated all config files** to `26MAY26`:\n - `config.py`: replaced `28APR26` with `26MAY26` in all four profiles (symbol_fut and expiry_date).\n - `lt_3candle_bot.py`: changed `SYMBOL_FUT` to `LT26MAY26FUT` and `EXPIRY_DATE` to `26MAY26`.\n - `lt_3candle_eod.py`: changed `SYMBOL_HIST` to `LT26MAY26FUT`.\n - Left `backtest_journal.py` unchanged (historical backtest data).\n\n4. **Restarted both bot services** and verified processes were running.\n\n5. **Fixed broker API session expiry**: Quotes/history endpoints returned HTTP 500 errors. Restarted OpenAlgo broker services (`openalgo-shoonya-...` and `openalgo-flattrade-...`) to re-authenticate. After restart, quotes returned 200 OK.\n\n6. **Verified live operation**:\n - Claude bot logs showed positions on new expiry: `DLF26MAY26585CE`, `INDUSINDBK26MAY26900CE`.\n - LT 3-candle bot showed `POLL | Futures=4081.7 | Bias=RED | Pos=NO` with May expiry.\n\n### Key Decisions & Outcomes\n\n- All active trading bots successfully rolled over to the May 2026 expiry.\n- The rollover required changes in three files; no code logic changes were needed.\n- Broker session expiry was an incidental issue resolved by restarting OpenAlgo services.\n\n### Performance Discussion & Mode Agreement\n\nThe user expressed frustration with processing time. The assistant acknowledged inefficiencies (sequential reads, multiple sleep waits, individual patches) and proposed a **two-mode system**:\n\n- **Thinking Mode** (default): careful step-by-step verification.\n- **Fast Mode**: parallel reads, batch file changes via `execute_code`, no sleep waits, poll logs for verification, skip redundant reads.\n\nThe user agreed, and the assistant saved this as a user memory. The user can toggle modes by saying \"s ... [9608 chars total, truncated]
