CELT/BTC Trading Precision Adjustment: Key Updates for Traders

The cryptocurrency market thrives on precision, speed, and user experience. To enhance trading efficiency and improve market liquidity, OKX has implemented important adjustments to the CELT/BTC trading pair. These changes focus on refining both the minimum price tick size and order quantity precision, ensuring smoother transactions and better alignment with evolving market demands.

This update, effective March 31, 2023, impacts spot trading for CELT/BTC and may also affect leveraged positions if applicable. While brief, the transition window requires attention from active traders to avoid unintended order cancellations or execution issues.

Below is a comprehensive breakdown of what changed, how it affects your orders and strategies, and what you should do next—especially if you're using APIs or automated trading tools.

🔧 Overview of Precision Adjustments

Precision settings determine how granularly traders can place orders in terms of price and volume. Adjusting these parameters helps standardize trading behavior, reduce system complexity, and increase matching efficiency across the order book.

Two core metrics were updated during a short maintenance window:

1. Trading Quantity Precision Adjustment

• Before: 0.0001
• After: 0.01
• Timeframe: 16:00 – 16:02 (UTC+8)

This change reduces the decimal places allowed when specifying how much CELT to buy or sell. It effectively increases the minimum trade increment, making smaller fractional trades invalid post-update.

2. Minimum Price Tick Size Adjustment

• Before: 0.00000001 BTC
• After: 0.0000000001 BTC
• Timeframe: 16:03 – 16:05 (UTC+8)

This update makes price steps finer, allowing for more precise pricing in the order book. Although counterintuitive, this enhances price discovery and supports tighter spreads—benefiting high-frequency and algorithmic traders.

During these transitions, CELT/BTC trading was paused for two minutes per adjustment, totaling up to five minutes of downtime. All other trading pairs remained unaffected.

⚠️ Risk Notice: What Traders Should Know

While the changes aim to improve long-term performance, short-term disruptions are inevitable. Here’s what happened during the adjustment period:

• Temporary trading suspension: The CELT/BTC pair was halted for 2 minutes per update.
• No new orders or modifications: Users could not place, cancel, or modify orders.
• No margin adjustments or fund transfers: Risk management actions were frozen temporarily.

To minimize risk:

• Cancel outdated limit orders before the maintenance window.
• Reduce exposure if holding leveraged positions.
• Reassess grid or bot-based strategies that rely on fine-grained quantities or prices.

📊 Order & Position Handling Rules

Understanding how existing orders and open positions are treated during precision changes is crucial for maintaining strategy integrity.

A. Trading Quantity Precision Changes

Case 1: Precision Decreased (from 0.0001 → 0.01)

When fewer decimal places are allowed:

• Orders with excessive decimals are canceled.

  • Example: An order for 8.0001 CELT is canceled because it exceeds the new 2-decimal limit.
  • An order for 8.01 CELT remains valid.
• Applies to all order types: limit, stop-loss, take-profit, and conditional triggers.

🔄 Strategy Impact:

• Grid trading, martingale bots (spot/grid/futures variants) will be terminated if their pending orders get canceled.
• Dollar-cost averaging (DCA), time-weighted buys, iceberg orders, arbitrage, and stop-limit plans will resume automatically after trading restarts—using updated precision.

Case 2: Precision Increased (Hypothetical reversal)

If precision were expanded back (e.g., from 0.01 → 0.0001):

• All current orders remain intact.
• No forced cancellations occur.

For API Traders:

• Orders submitted via API using old precision (e.g., 4 decimals) are automatically truncated to fit the new standard.
• Example: Sending 8.0099 becomes 8.00 (truncated, not rounded).
• Web and mobile users cannot submit such orders at all—they’re blocked at input.

B. Minimum Price Tick Size Changes

Case 1: Tick Size Decreased (from 0.00000001 → 0.0000000001)

This allows much finer pricing:

• Existing orders with prices beyond the new tick rule (i.e., too many decimals) are canceled.

  • Example: A buy order at 0.000002345 BTC would be canceled if only increments of 0.000000001 BTC are allowed.
• Valid orders (aligned with new ticks) remain active.

🔄 Strategy Impact:

• Same as above: grid/martingale strategies terminate upon cancellation; others persist and reapply under new rules.

Case 2: Tick Size Increased (Hypothetical)

All existing orders survive—no cancellations.

Display Rules for Historical Data:

• After reducing precision:

  • Web and mobile users see historical prices/amounts rounded to new standards:

    • Buy orders: truncated (floor)
    • Sell orders: rounded up (ceiling)
  • API users retain original precision in logs and responses.

❓ Frequently Asked Questions (FAQ)

Q1: Why did OKX reduce the quantity precision from 4 decimals to 2?
A: Reducing decimal places simplifies order handling, improves system performance, and discourages spammy micro-orders that don’t contribute meaningfully to liquidity.

Q2: Will my open grid trading bot be affected?
A: Yes. If any pending order violates the new precision rules, the entire grid strategy will be terminated automatically. You’ll need to recreate it post-update.

Q3: Can I still use API to trade with higher precision?
A: No—your input will be truncated to match the new standard. For example, sending 8.9999 when only 8.99 is valid results in 8.99. Always validate your payload format.

Q4: Were leveraged positions impacted?
A: If CELT/BTC had leveraged markets active at the time, those would have been adjusted simultaneously. However, spot-only users weren’t exposed to additional margin risks.

Q5: How can I prepare for future updates like this?
A: Regularly monitor official announcements, set alerts for maintenance windows, and build flexibility into automated systems by validating inputs against current exchange rules.

Q6: Is this change permanent?
A: Unless otherwise announced, yes. Future adjustments depend on market conditions and user feedback.

✅ Final Thoughts

The CELT/BTC precision update represents a step forward in creating a more robust and responsive trading environment. While temporary disruptions occurred, the long-term benefits—such as improved liquidity, cleaner order books, and better API consistency—are significant.

Traders should review their open orders, refine bot configurations, and stay informed about upcoming platform changes to remain competitive.
