Volatility-Adaptive Quotes and Inventory Control for Intraday Strategies

Summary

The document reviews weaknesses in high-frequency and market-making approaches that place orders too close to the market. During sharp one-minute moves, nearby orders can accumulate inventory quickly, increasing stop-out risk and slippage. It suggests measuring the largest candle-body move over the recent 20 bars and using that volatility estimate to adjust quote distance, widening quotes during volatile periods and returning toward normal as volatility falls.

For inventory, it proposes aiming to stay near flat and clearing positions within minutes, first trying maker execution and then using a trailing stop or a market order if needed. It also notes that hedging futures exposure with spot can reduce directional risk but requires more capital and adds costs. Quote placement and fixed take-profit levels should both respond to current volatility. These are practical suggestions rather than a tested strategy: the document offers a DOGE example of extreme one-minute candles but provides no systematic performance evidence or parameter validation.

Key ideas

• Use recent candle-body volatility to adapt quote distance.
• Widen orders when short-term volatility rises to limit rapid inventory buildup.
• Keep inventory near flat and define a prompt process for liquidating positions.
• Spot hedges can reduce exposure but may add capital and transaction costs.
• Adjust take-profit levels, and potentially stops, to reflect changing volatility.
