People using Pionex often see three bots in the backend—“Classic Grid,” “Infinite Grid,” and “Martingale Strategy”—that look similar but have completely different mathematical models. Picking the wrong type costs way more than tuning parameters poorly. This post breaks down the core differences and helps you choose the right bot for your situation.
Understand the Essence in One Chart
| Strategy | Core Assumption | Profit Condition | Max Risk |
|---|---|---|---|
| Classic Grid | Price oscillates within a range | Repeated back-and-forth within bounds | Break below floor with large position |
| Infinite Grid | Long-term uptrend with pullbacks | Buy on each dip, sell on rallies | Sustained drop breaking the floor |
| Martingale | Inevitable rebound after decline | Single bounce recovers losses + profit | Liquidation on continuous decline |
The fundamental difference is market assumptions—get them wrong and losses follow.
Classic Grid (Spot Grid)
Logic: Within a fixed price range (e.g., BTC $60,000–$70,000), divide the range into N grids with buy and sell orders at each level. When price drops to a level, it triggers a buy; when it rises to the next level, it triggers a sell. You profit from the per-grid spread.
Mathematical Model:
Per-grid profit rate = grid spacing / buy price - 2 × fee
Typical Use Cases:
- BTC, ETH oscillating between known support and resistance
- Stablecoin pairs (e.g., DAI/USDT arbitrage—minimal volatility but viable)
- Gold, silver, and other traditional oscillating assets
Not Suitable For:
- One-way rallies (you’ll miss out)
- One-way declines (you’ll carry heavy unrealized losses)

Infinite Grid
Logic: No upper limit, only a lower floor. When price rises X%, you sell a portion; when it pulls back X%, you buy again. In theory, no matter how high price goes, you won’t miss out.
Mathematical Model:
Divide capital into N portions
Buy 1 portion at current price on entry
Sell 1/N of holdings on each X% rally
Buy 1 new portion on each X% pullback
Key Parameters:
- Floor price (worst-case drop threshold)
- Per-grid movement (recommended 1.5–3%)
- Capital allocation (recommended 10–20 portions)
Typical Use Cases:
- You’re bullish on a coin long-term but expect a bumpy path (like BTC)
- You want to “buy the dips” without letting emotions drive decisions
- Ideal for extracting more gains from trending markets
Real-World Example (BTC/USDT):
- Starting price $65,000, floor $40,000, 10 portions of $100 each
- Over 30 days, BTC rises from $65,000 to $72,000
- Infinite Grid yield: ~$180 (18% APY annualized)
- Straight HODL: +10.8%
- 7 percentage points better than HODL, but requires active rebalancing
Risks:
- BTC breaks below $40,000 floor → you can’t buy anymore, capital sits idle
- During declines, you buy at every grid level, so unrealized losses grow first
Martingale Strategy
Logic: Every X% price drop, you increase your position (bigger drops mean bigger increases). When price bounces to a target level, you close everything for profit.
Mathematical Model (Pionex Martingale):
First buy: $S
1st drop of –3% → buy 1.5×S (multiplier)
2nd drop of –3% → buy 1.5²×S
3rd drop of –3% → buy 1.5³×S
...
Rally to first buy price × (1+y%) → sell all
Core Risk: Continuous declines consume capital exponentially.
Pionex default: 1.5x multiplier, 15 levels
Total capital needed after 15 levels = S × (1.5^15 - 1) / 0.5 ≈ 876 × S
You think $100 is enough, but you actually need $87,600 to complete all 15 levels
Typical Use Cases:
- Low-volatility markets (BTC consolidating during bull runs)
- Absolute confidence the coin won’t drop more than 50%
- Ample capital (recommend 10x your visible parameters)
Not Suitable For:
- Bear markets (you’ll go bankrupt holding)
- Low-cap coins (may go to zero)
- Beginners (parameters look profitable but liquidation risk is massive)
Quick Comparison
| Classic Grid | Infinite Grid | Martingale | |
|---|---|---|---|
| Best For | Range-bound markets | Long-term uptrend + volatility | Short-term bounce after drop |
| Per-Trade Profit | Fixed (grid spread) | Fixed (per-grid rise) | Rebound threshold |
| Max Risk | Holding at range floor | Sustained break below floor | Liquidation on continuous decline |
| Capital Efficiency | Low (evenly distributed) | Medium | Highest (but highest risk too) |
| Learning Curve | ⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐⭐ |
| Beginner-Friendly | ✅ | ⚠️ requires reading the trend | ❌ too many pitfalls |
My Selection Strategy
Over the past year, I’ve run all three simultaneously:
- Infinite Grid for BTC/ETH (I’m bullish long-term but want to capture intermediate volatility)
- Classic Grid for gold (clear range oscillation)
- Martingale only on quality coins that have already dropped 20%+ with small test amounts (and 10x capital reserve)
I never put large capital into Martingale. Even when returns look highest.
How to Get Started
Any bot on Pionex supports backtesting (run historical data from the past 30/90 days to see results). First compare a few parameter combinations, then run the smallest amount for 2 weeks to gauge your emotional tolerance for unrealized losses, then scale up.
→ Start your first grid bot on Pionex
Summary
- Classic Grid: Most stable, best for ranging markets and beginners
- Infinite Grid: Best for coins you’re bullish on long-term with clear volatility
- Martingale: Looks most profitable, actually easiest to liquidate—only for experienced traders with ample capital
Picking the wrong type beats poorly-tuned parameters every time. First figure out what market regime you’re in, then choose the matching bot.
