Trading 0DTE With Gamma Levels
0DTE trading around gamma levels rewards patience far more than speed, because the levels that matter are known before the session opens.
How does the Obsidian desk trade 0DTE with gamma levels?
The Obsidian desk marks the 0DTE call wall, put wall and gamma flip before the open, then waits for price to reach one of those three levels rather than trading between them. Trades taken between marked levels carry no structural edge and consume the session's risk budget.
What time of day do 0DTE gamma levels work best?
0DTE gamma levels strengthen through the session as time value collapses and hedging tightens. The Obsidian desk finds the window from late morning through the final two hours most reliable, while the first thirty minutes produces the highest rate of false reactions.
How should a trader size a 0DTE position?
0DTE contracts can lose the majority of their value within minutes, so the Obsidian desk sizes each 0DTE position on the assumption that the full premium may be lost. Risk per trade is fixed as a small percentage of account equity before entry, never after.
When should a trader avoid 0DTE entirely?
The Obsidian desk avoids 0DTE contracts on days with a scheduled macro release inside the intended holding window, on sessions where positioning is spread evenly with no dominant level anywhere near price, and whenever the trader has already taken two consecutive losses during that same session.
