How does AskPriceBufferPer affect slippage?

AskPriceBufferPer directly impacts the trade-off between execution likelihood and slippage when placing limit or hybrid orders in MagicTradeBot.

It determines how much extra you are willing to pay above the current ask price to secure a fill.

🔹 Understanding the Effect

  1. Small Positive Buffer (>0)

  2. Slightly increases your limit price above the current ask

  3. Example:

    Best Ask = $100
AskPriceBufferPer = 0.1
Limit Price = 100 + (100 × 0.1 / 100) = 100.10

  4. Effect:

    • Execution probability increases, especially in volatile markets
    • Slippage is small but controlled (+$0.10 in the example)
    • Reduces missed trades while keeping cost predictable

  1. Zero Buffer (0%)

  2. Order is placed exactly at the current ask price

  3. Example:

    Best Ask = $100
AskPriceBufferPer = 0
Limit Price = 100

  4. Effect:

    • No additional slippage (exact cost)
    • Higher risk of unfilled orders if price moves quickly
    • May miss entry opportunities in fast-moving markets

🔹 Key Trade-Off

AskPriceBufferPer Slippage Impact Fill Probability Best Use Case
0% None Low in volatile markets Calm/liquid markets
0.05% – 0.2% Minimal Improved Standard crypto trading
0.3% – 0.5%+ Slight High Fast-moving, high-volatility pairs
  • Higher buffer → more likely to fill, slightly higher price
  • Lower buffer → precise price, but may miss fills

🔹 Practical Tips

  1. Scalp or HFT Strategies: Use a small buffer (0.05%–0.1%) to reduce missed trades without significant slippage.

  2. Day Trading or Calm Markets: Zero or minimal buffer is sufficient; price movement is less aggressive.

  3. Volatile Crypto Pairs: Slightly higher buffer (0.2%–0.5%) ensures trades are executed while keeping slippage predictable.

  4. Monitor Performance: Adjust dynamically depending on market volatility; high slippage can erode profits if the buffer is too large.

🔹 Key Takeaway

AskPriceBufferPer allows you to control the balance between slippage and execution certainty:

  • Small positive buffer → slightly higher price, better fills
  • Zero buffer → exact price, risk of missed orders

It is an essential setting to maintain consistent trade execution without sacrificing risk management, especially in fast-moving markets.
