A plain long grid becomes increasingly directional as price approaches one side of its range. This page models how a hypothetical allocation between the grid and a short hedge changes the boundary outcomes.
The calculation mechanically selects a split that reduces the difference between the two modelled boundaries. It is not a recommendation or suitability assessment, and real execution can differ materially.
The amber line shows a pure long grid using the full capital. The cyan line shows the hybrid structure, where part of the capital funds the short margin and the rest remains in the grid.
The sizing engine aims to pull both edges of the range toward a similar net outcome, reducing the wide gap between a weak upside and a painful downside.
Price hits $80.00 (-20%)
Price hits $120.00 (+20%)
This table decomposes the hedged structure itself. The pure full-capital grid remains in the chart above as a benchmark, but the rows below use the actual post-split grid capital so the totals add up cleanly.
| Scenario | Grid leg | Short leg | Combined |
|---|---|---|---|
| Price -> $80.00 | -12.86% | +8.57% (+$85.71) | -4.29% |
| Price -> $120.00 | +4.29% | -8.57% (-$85.71) | -4.29% |
Grid trading usually pays you a little when price rises and hurts much more when price sinks through the lower side of the range. By pairing it with a short, you are not trying to eliminate every risk. You are trying to make the shape of the payoff more civilized.
Most traders know they want a hedge, yet many still size it by intuition. That is where setups become inconsistent. An automatic split gives you a repeatable starting point, so each new range begins from a framework instead of a hunch.
This model does not include funding, liquidation mechanics, slippage, or execution latency. It is best used as a scenario map. If the boundary outcomes already look uncomfortable here, real trading conditions rarely make them gentler.
