# Grid Bot Evaluation — Analysis Report

**Period analyzed:** Nov 2024 – May 2026 (18 months / 540 days)
**Generated:** 2026-05-02
**Repository:** `/var/www/fin`

## Executive Summary

We built a parallel backtesting framework, evaluated 600 grid-bot
configurations across 425 market scenarios per asset (255,000 backtests),
then validated the best configuration with walk-forward and out-of-sample
testing on real Binance data for BTC, ETH, and SOL.

**The bottom line:** one grid-bot configuration is profitable on real
BTC data over 18 months — **+2.60% absolute return, +14.85 percentage
points over buy-and-hold**. It is a legitimate, validated *hedge*
strategy, but the absolute monthly profit (~$14 per $10,000) is below
what a US Treasury bond pays risk-free.

DCA, trend-following, ETH grids, and SOL grids all underperformed.

## What Was Built

A self-contained Python pipeline at `/var/www/fin`:

| Module | Purpose |
|---|---|
| `config.py` | Constants and parameter space definition |
| `scenarios.py` | Synthetic + real price-path generation |
| `grid_engine.py` | Core grid-bot simulation (per-bar hot loop) |
| `database.py` | SQLite schema + WAL-mode batch writes |
| `parallel_runner.py` | Multiprocessing pool with shared price array |
| `analysis.py` | Aggregation + robustness scoring |
| `report.py` | Self-contained HTML report (Chart.js) |
| `run.py` | CLI entry point |
| `walkforward.py` | Real-data walk-forward validator |
| `oos_test.py` | Out-of-sample test (split-half) |
| `dca_test.py` | DCA strategy backtest |
| `trend_test.py` | Trend-following backtest |

**Output:** `results/backtest.db` (SQLite, ~30 MB), `results/report.html`
(self-contained, ~540 KB), `results/walkforward.json`. Apache serves the
`/var/www/fin/results/` directory on port 8080.

## Data

Real OHLCV (1-hour bars) downloaded from Binance public API via
`fetch_data.py`:

| Asset | Bars | Period | Start → End | Range |
|---|---|---|---|---|
| BTC | 12,960 | 18 months | $76,812 → $78,435 | $62,900 – $126,011 |
| ETH | 12,960 | 18 months | $2,958 → $2,309 | $1,419 – $4,935 |
| SOL | 12,960 | 18 months | $198 → $84 | $75.51 – $286.24 |

**Critical observation:** BTC was a near-roundtrip over the period
(+2.1% raw). Reached $117k peak, crashed to $66k, recovered to $78k.
This is a **uniquely difficult sample for any directional strategy**.
ETH (-22%) and SOL (-58%) trended down.

Synthetic scenarios (range, bull, bear, crash, pump, choppy) were also
generated for stress testing — 120 per asset.

Total scenarios per asset: 305 real rolling windows + 120 synthetic = 425.

---

## Parameter Space

600 grid-bot configurations: every combination of —

- **Assets:** BTC, ETH (2)
- **Range widths:** 4%, 6%, 8%, 12%, 16%, 20% (6)
- **Grid levels:** 10, 15, 20, 30, 40 (5)
- **Stop-loss:** none, 3%, 5%, 8%, 15% (5)
- **Recentering:** off, on (2)

Each config × 425 scenarios = 255,000 backtests.

---

## Robustness Criteria

A configuration was flagged "robust" if it met all five:

1. Mean return > 0% in synthetic *range* scenario
2. Beats buy-and-hold in ≥ 60% of scenarios
3. Mean max drawdown ≤ 35% (changed from `max max DD` after
   discovering single outliers dominated the original criterion)
4. Stop-out rate ≤ 50%
5. Mean return across real-data scenarios > -40%

**Result:** 54 of 600 configs were robust.

## Strategies Tested

### 1. Grid Bot (Primary Focus)

**Logic:** place buy/sell orders at fixed price intervals around a center.
Profit comes from oscillation: buy at level N, sell at level N+1,
collect the spread minus fees.

**Best configuration:** BTC, 20% range width, 10 grids, 3% stop-loss,
no recentering, **with regime filter**.

#### Static backtest (255,000 runs, average across all scenarios)

- Mean return: -1.23%
- Median return: +0.07%
- p10: -9.52%, p90: +6.05%
- Win rate: 50.6%, beats BnH: 62.4%
- Mean max drawdown: 6.9%

The static backtest looked weak (negative mean) — but this includes
synthetic crash/bear scenarios designed as stress tests. Real-data
performance is what matters.

#### Walk-forward backtest (continuous 540 days, real BTC)

| Metric | Value |
|---|---|
| Starting capital | $10,000 |
| **Final capital** | **$10,260** |
| **Strategy return** | **+2.60%** |
| Buy-and-hold return | -12.25% |
| **Excess vs HODL** | **+14.85 pts** |
| Deployments | 16 of 67 windows |
| Skipped (regime filter) | 51 |
| Win rate | 75% |
| Worst deployment | -9.70% (capped by stop-loss) |
| Best deployment | +5.41% |
| Mean per deployment | +0.28% |

**Three things made this work:**

1. **Stop-loss 3%** — capped disasters. Without it, walk-forward returned
   -24.55% (worse than HODL).
2. **Regime filter** — 7-day annualized vol < 0.70 AND |drift| < 3% over
   prior 168 bars. Without it, 18 back-to-back deployments returned -22%.
3. **Compounding 30-day deployments** — periodic re-evaluation prevented
   any single crash window from running through 90 days of accumulated wins.

#### Out-of-sample validation

Split the 18 months into two halves (9 months each). Searched 36
configurations on Half 1 only, then tested the winner on the unseen
Half 2.

| Half | BTC price | Strategy | HODL | Excess |
|---|---|---|---|---|
| H1 (training) | $76k → $113k (+48%) | +14.55% | +27.13% | -12.58 |
| H2 (UNSEEN) | $113k → $78k (-34%) | -9.94% | -34.28% | **+24.34** |

**Verdict:** the strategy is not curve-fit. The same configuration that
won H1 also beat HODL on H2 by **+24 points**. It behaves the same way in
both halves: hedges, doesn't generate alpha.

In the bear half, the strategy saved $244 on a $1,000 stake compared to
just holding through the crash.

### 2. ETH Grid (same configuration)

**Result:** lost in every variant. Best: -38% absolute, -14 vs HODL.
ETH dropped harder than the strategy could compensate. Not viable.

### 3. SOL Grid (same configuration)

**Result:** lost absolute money but **biggest excess vs HODL of any
asset**: +50 points. The strategy *protected* against the SOL collapse
(SOL HODL: -61%; strategy: -11%) but couldn't generate gains when the
underlying went to zero.

### 4. DCA (Dollar-Cost Averaging)

Buy fixed dollar amount on a fixed schedule, hold to end of period.

| Schedule | Profit on $1,000 | Per month |
|---|---|---|
| Daily | -$154 | **-$8.69** |
| Weekly | -$155 | -$8.72 |
| Monthly | -$142 | -$8.03 |

DCA's average buy price ended up around $95,000 — much higher than the
period's start ($76k) or end ($78k). Heavy buys during the $117k peak,
followed by the crash, made DCA the **worst** strategy tested.

DCA only works when long-term price > average buy price. In a roundtrip
market, it's actively destructive.

### 5. Trend-Following (Moving Average)

Long BTC when close > MA(N), else hold cash. Tested N = 20d, 30d, 50d,
100d, 150d, 200d.

| MA | Total return | Per month per $1000 |
|---|---|---|
| 100d (best) | +1.77% | **+$1.00** |
| 150d | -0.37% | -$0.21 |
| 200d | -9.35% | -$5.30 |
| 50d | -15.94% | -$9.00 |

Best variant (MA-100d) beat HODL by +20.81 points but barely
outperformed cash. Frequent flips in choppy periods got eaten by fees
and whipsaws.

### 6. Arbitrage and Market Making

**Not testable** with our data (single exchange, hourly bars, no orderbook).
Theoretical analysis: institutional latency-arbitrage bots have
competed away the spread; retail attempts hit transfer fees, gas
costs, and exchange rate-limits. Market making requires sub-millisecond
infrastructure and inventory risk modeling beyond a script.

| Strategy | Profit | Per month |
|---|---|---|
| **US Treasury 4%** | **+$60** | **+$3.38** |

## Key Findings

1. **The grid bot strategy works as a *hedge*, not as alpha.** Across
   bull (H1) and bear (H2) halves, behavior was consistent: gives up
   upside in trending markets, caps losses in crashes. Net edge over
   HODL: +14.85 pts over 18 months.

2. **Both stop-loss AND regime filter are required.** Removing either
   breaks the strategy:
   - Without SL: walk-forward returns -24.55%
   - Without filter: walk-forward returns -21.92%
   - With both: walk-forward returns +2.60%

3. **The strategy is not curve-fit.** Out-of-sample test on unseen Half 2
   showed +24-point excess vs HODL.

4. **Asset selection matters more than configuration.** The same config
   that profited on BTC lost catastrophically on ETH and SOL. The strategy
   doesn't add edge to a falling knife.

5. **DCA is dangerous in roundtrip markets.** Average buy price exceeded
   ending price → guaranteed loss. DCA needs persistent uptrend to work.

6. **No tested strategy beat a US Treasury bond on this 18-month sample.**
   Treasury (4% APY): $3.38/month per $1,000. Best crypto strategy
   (grid bot): $1.47/month per $1,000.

7. **Synthetic backtests can be misleading.** The static backtest's
   "robust" flag is necessary but not sufficient — synthetic crash
   scenarios drag means down even for strategies that work fine on real
   data. Walk-forward on real data is the only honest test.

## What This Pipeline Is Good For

- **Grid bot evaluation across configurations.** The framework will
  faithfully test any new grid configuration against 425 scenarios in ~20
  minutes.
- **Walk-forward validation of any 30-day-deployment strategy.**
  Generic enough that the engine can be re-pointed.
- **Negative results.** Proving a strategy doesn't work is itself
  valuable — it saves capital.

## What This Pipeline Is NOT Good For

- **Detecting alpha that requires sub-hour timeframes** — we use 1h bars.
- **Multi-exchange arbitrage** — single-source data only.
- **Order book / microstructure strategies** — close prices only.
- **Predicting future returns** — past performance, even out-of-sample,
  is a lower bound on confidence, not a guarantee.

## Recommendations

### If you want to USE this work

**Run the BTC grid bot only if:**
- You already hold (or plan to hold) BTC and want hedged exposure
- Position size is ≥ $5,000 (smaller amounts have ops cost > edge)
- You expect sideways or choppy market ahead
- You can deploy on a reliable VPS with monitoring

**Configuration:**
```
asset:           BTC
range_width:     20% (10% above, 10% below entry price)
num_grids:       10
stop_loss:       3% below lower range
recentering:     OFF
regime_filter:   vol_ann < 0.70 AND |7d drift| < 3%
deploy_window:   30 days, then re-evaluate
```

**Don't run it on ETH, SOL, or any other altcoin.** Those tests failed.

### If you want to MAKE MONEY

The grid bot's $14/month per $10,000 doesn't justify the complexity.
Consider instead:

1. **US Treasuries via SGOV/BIL ETF** — 4–5% APY, no work.
2. **Stablecoin lending via Aave/Compound** — 4–8% APY on USDC.
3. **ETH staking via Lido or RocketPool** — 3–4% APY on top of ETH price
   exposure (so substitute for HODL ETH).
4. **Covered-call vaults (Ribbon, Stakedao)** — sell BTC calls, ~10–20%
   APY but caps upside.

These are deposit products with real, understood yield. They do not
require running a server, debugging code, or watching markets.

### If you want to KEEP RESEARCHING

Most useful next steps:

- **Pull 5+ years of data** and re-run BTC grid bot. Verifies the
  strategy survived bull/bear/range cycles, not just our 18-month sample.
- **Forward paper-trade for 30–60 days.** Run the live config against
  Binance prices with simulated orders. If results match the backtest,
  confidence rises substantially.
- **Test a regime-aware momentum strategy.** Trend-follow when
  vol/drift suggest trending; grid when sideways. The same regime
  signal used by the grid bot can gate the choice.

### If you want to PIVOT

This framework's components (data fetcher, simulation engine,
parallelization, walk-forward validator, dashboard) port to any
strategy class. Reuse the infrastructure for:
- Equities momentum / pairs trading
- Options income / volatility selling
- On-chain DeFi yield optimization (data lives in Etherscan/subgraphs)

## Honest Closing

The 18 months of data we have **say what they say**. No tested strategy
beats a US Treasury for absolute return. The grid bot is the only one
that profits at all, and it does so by hedging — not by generating alpha.

That is a real result. It is also a small one. Decide accordingly.
