Perpetual Futures
MegaTAO perpetual futures are derivative contracts that track Alpha token prices. They never expire, allowing you to hold a position indefinitely (subject to funding costs, interest fees, and margin requirements).
Positions
A position is an open trade representing exposure to an Alpha token price.
Long position: Profits when the Alpha token price goes up. You are buying exposure.
Short position: Profits when the Alpha token price goes down. You are selling exposure.
Each trader can hold one position per market. Position IDs are deterministically derived from the trader address and market address. A trader can hold up to 50 positions across different markets.
Leverage
Leverage multiplies your position size relative to your margin.

How leverage affects P&L
With 5x leverage:
Price moves +10% --> your margin gains +50%
Price moves -10% --> your margin loses -50%
Price moves -10% --> liquidation (at 10% maintenance margin)
Leverage amplifies both gains and losses equally.
Margin
Margin is the TAO collateral that backs your position.
Initial margin
The margin required to open a position:
Maintenance margin
The minimum margin ratio required to keep a position open. This is configured per-market (currently 10% on all markets, configurable from 1% to 50%).
If your margin ratio falls below the maintenance margin, the position is liquidated. See Liquidations.
Margin ratio
Order execution
All positions are opened and closed via market orders. The order is first routed to the orderbook for matching. If no match is found, the protocol vault fills it.
Execution includes dynamic slippage based on position size and vault utilization:
Normal
0.1%
Medium
0.15%
High
0.25%
Maximum slippage is capped at 20%. You set a maxSlippage parameter when opening a position, and the transaction reverts if actual slippage exceeds it.
A 0.25% trading fee is charged on the notional value of each trade (both open and close). See Fees.
Closing positions
You can close a position at any time:
Full close: Close the entire position
Partial close: Close a portion of the position by specifying a notional amount
A position cannot be opened and closed in the same block (flash loan protection).
