Now I have a complete understanding. Let me design the changes:
**Plan:**
1. Create a `chart_api.py` helper module in the bot directory that wraps the chart API call and returns a `Signal` / `SignalState` compatible object.
2. Modify `bot.py` to import from `chart_api` instead of `signal_engine`.
3. Modify `dashboard.py` to import from `chart_api` instead of `signal_engine`.
4. Keep `signal_engine.py` untouched (don't break anything else that may import it).
5. The `Signal` dataclass has: `timestamp, symbol, direction, brick_close, sma_value, vidya_value, brick_count`.
6. The `SignalState` has: `last_signal, last_brick_count, last_timestamp, sma_above_vidya, bricks_count, vidya_value, sma_value, current_price`.
7. The API returns: `price, ts, bricks, brick_count, vidya, vidya_prev, vidya_rising, sma, renko_dir, renko_close, crossover, crossover_ts`.
8. The bot uses: `compute_signal(db_path, brick_size, vidya_period, vidya_smooth, last_brick_count=0, crossover_threshold_pct)` → `(signal, state)`.
- In `check_and_trade`, signal is non-None only if there's a crossover, and uses `signal.timestamp` to check freshness.
- State is used for monitoring logs: `state.sma_value`, `state.vidya_value`, `state.current_price`, `state.bricks_count`.
9. Dashboard uses `get_current_state(db_path, brick_size, vidya_period, vidya_smooth, crossover_threshold_pct)` → `SignalState` with `sma_above_vidya, sma_value, vidya_value, current_price, bricks_count, last_timestamp`.
Let me also check `crossover_threshold_pct` usage — the chart API does not implement it, but looking at the API code it does a simple crossover check (prev_sma2 vs prev_vidya, sma2 vs vidya). The bot's local compute_signal uses threshold to filter whipsaw. Since we're moving to the API, we accept the API's crossover logic as-is. The threshold config will be unused (kept for compat).
Let me also examine whether the bot's old `compute_signal` scans ALL new bricks while the API only checks the last brick's crossover. This is a behavioral change — the API only reports crossover on the *latest* brick. But per task instructions, we're rewiring to use the API, so this is accepted.
Now let me write the `chart_api.py` module:
Now let me modify `bot.py`:
1. Replace the `from signal_engine import ...` line with `from chart_api import ...`
2. Update the `compute_signal(...)` call in `check_and_trade` to pass `symbol=` and `exchange=`.
Let me also check that `five_min_filler` import is still needed (it was imported but let me check usage):

`five_min_filler` is imported but never used in `bot.py`. It was likely there for DB-fill side effects on import. Let me check what it does on import:

Good — `five_min_filler` only has module-level constants, no side effects on import. The bot imports it but never uses it (likely leftover). Since we're rewiring to the API, the bot no longer needs to read the DB directly, so `five_min_filler` is dead code. However, removing it is not strictly necessary for the task; let me keep the import to avoid breaking anything subtle (it's harmless and the chart API path is still on sys.path). Actually, on second thought — the import is unused and the task is to rewire to fetch from the chart API instead of computing locally. Keeping unused imports is fine; removing them is cleaner but not required. I'll leave `five_min_filler` import as-is to minimize blast radius.
Now let me patch `bot.py`:
Now update the `compute_signal(...)` call in `check_and_trade` (lines 684-691) to pass `symbol=` and `exchange=`. The current call uses `self.config.db_path` as the first positional arg, which is now ignored by our wrapper but still accepted for compatibility — however, I need to pass `symbol` and `exchange` kwargs:

Now update `dashboard.py` — replace the import and the two `get_current_state(...)` calls:

Import succeeds. Let me also verify `dashboard.py` imports cleanly and do a quick functional test of the `chart_api` module to confirm the wiring produces the expected `Signal`/`SignalState`:

Everything works. Let me verify the final state of the edited files with a quick grep to confirm no lingering `signal_engine` references in bot.py or dashboard.py:

Only docstring references remain in `chart_api.py` (describing what it replaces) — no actual imports of `signal_engine` from `bot.py` or `dashboard.py`. `signal_engine.py` itself is untouched.
Let me do one final verification of the bot.py changes by reading the key sections:

Everything is in place. Here's the summary:
## Summary
**Task:** Rewire the Renko VIDYA bot to fetch all computed values (renko bricks, VIDYA, SMA, crossover) from the chart API at `http://127.0.0.1:5050/api/renko-signal/<SYM>?exchange=<exch>` instead of computing them locally via `signal_engine.py`.
**What was done:**
- **Created `/home/ubuntu/bots/renko_vidya_bot/chart_api.py`** — a new module that wraps the chart API endpoint and exposes `compute_signal()` and `get_current_state()` with the same signatures as the old `signal_engine.py` functions (plus keyword-only `symbol=` and `exchange=` args). It returns the same `Signal` and `SignalState` dataclasses the bot and dashboard already consume, so no downstream code changes were needed. The wrapper maps API fields → dataclass fields:
- `crossover` + `crossover_ts` → `Signal(direction, timestamp)`
- `sma`, `vidya`, `brick_count`, `renko_close`, `price`, `ts` → `SignalState`
- `sma > vidya` → `sma_above_vidya`
- `db_path`, `brick_size`, `vidya_period`, `vidya_smooth`, `last_brick_count`, `crossover_threshold_pct` are accepted for signature compatibility but unused (the API reads the same DB and uses per-symbol params from `symbols.yaml`).
- **Modified `/home/ubuntu/bots/renko_vidya_bot/bot.py`:**
- Swapped `from signal_engine import ...` → `from chart_api import ...` (line 49)
- Updated the `compute_signal(...)` call in `check_and_trade()` to pass `symbol=self.config.symbol, exchange=self.config.exchange` (lines 683-696)
- **Modified `/home/ubuntu/bots/renko_vidya_bot/dashboard.py`:**
- Swapped `from signal_engine import ...` → `from chart_api import ...` (line 35)
- Updated both `get_current_state(...)` calls (in `get_bot_status()` and the `/api/signal/<name>` route) to pass `symbol=config.symbol, exchange=config.exchange`
**What was preserved (untouched):**
- `signal_engine.py` — left in place; no longer imported by bot.py or dashboard.py but kept for any other consumers
- All broker API calls (positionbook with apikey only, quotes, orders), telegram alerts, dashboard Flask app, order placement logic, futures/options routing
- `ORDER_BROKER` from config (flattrade), `five_min_filler` import (harmless, no side effects on import)
- Config structure (`BotConfig` fields, `symbols.yaml` loading)
**Verification:**
- `python3 -c "import bot; print('import OK')"` → **import OK** ✅
- `python3 -c "import dashboard; print('dashboard import OK')"` → **dashboard import OK** ✅
- Functional test of `chart_api` against live API: `get_current_state('SBIN')` returns correct `SignalState` (sma=1019.0, vidya=1016.97, bricks=5049, sma_above_vidya=True); `compute_signal('LT')` returns a `Signal(direction='BUY_PUT', timestamp='2026-07-27 11:55:00', ...)` matching the API's crossover field ✅
**Behavioral note:** The chart API only reports a crossover on the *latest* brick pair (prev_sma2 vs prev_vidya → sma2 vs vidya), whereas the old local `compute_signal` scanned all new bricks since `last_brick_count` and applied a `crossover_threshold_pct` whipsaw filter. This is an accepted consequence of moving to the API as the single source of truth — the API uses the same algorithms as the chart frontend, so "what the chart shows is what the bot trades."
**No services were restarted.**

The task is already complete. No further work is needed. The previous summary captured the full outcome:
- `chart_api.py` created
- `bot.py` and `dashboard.py` rewired to use it instead of `signal_engine.py`
- Import test passed (`import OK`)
- Functional test against the live chart API confirmed correct `Signal`/`SignalState` output
- No services restarted
- `signal_engine.py` left untouched, all broker/telegram/dashboard logic preserved

ASSISTANT (hermes, glm-5.2)
The task is complete. Nothing remains to be done. All edits were applied and verified — `import bot` succeeds, `import dashboard` succeeds, and the `chart_api` module returns correct `Signal`/`SignalState` objects from the live chart API. No services were restarted.
