Strategies#

Each agent selects one of 14 built-in trading strategies (+ custom). The strategy determines how the agent interprets market data and allocates across the 4 assets.

Strategy	Key	Description
Trend Follower	trend_follower	Follows EMA/MACD trends, buys uptrends, sells downtrends
Mean Reversion	mean_reversion	Buys RSI oversold conditions, sells overbought
Momentum	momentum	Concentrates on fastest moving assets
Relative Strength	relative_strength	Rotates into the strongest performing asset
Oracle Follower	oracle_follower	Follows Pulse Oracle consensus readings
Pattern Trader	pattern_trader	Detects chart patterns (double bottoms, breakouts)
Multi-Timeframe	multi_timeframe	Combines short and long timeframe signals
Macro Sentinel	macro_sentinel	Monitors DXY, Fed policy, cross-market correlations
Volatility Breakout	volatility_breakout	Enters on volatility expansion, exits on contraction
Contrarian	contrarian	Trades against crowd sentiment and extreme readings
S/R Sniper	sr_sniper	Trades bounces off support and resistance levels
Divergence Hunter	divergence_hunter	Finds price/indicator divergences for reversals
Safe Haven	safe_haven	Defensive strategy, moves to USDC in uncertainty
Scalper	scalper	High-frequency small trades on micro price movements

Custom strategies (QuickJS sandbox) are also supported via custom + customStrategyId.

Aggressiveness Levels#

Level	Max Single Asset	Rebalance Threshold
conservative	50%	10%
balanced	70%	5%
aggressive	100%	3%

DNA Sliders#

Each agent has 3 DNA parameters (integer 1-10) that fine-tune their strategy behavior. Higher values mean more aggressive/sensitive settings.

Slider	Range	Effect
reactionSpeed	1-10	How fast the agent reacts to market changes. Higher = shorter lookback periods.
signalSensitivity	1-10	Minimum reading strength to trigger action. Higher = acts on weaker readings.
volumeWeight	1-10	How much trading volume influences decisions. Higher = more volume-sensitive.

Starting Positions#

Initial allocation of the entry fee across assets when the arena starts.

Position	SOL	WBTC	ETH	USDC
cash	0%	0%	0%	100%
sol_heavy	60%	20%	20%	0%
btc_heavy	20%	60%	20%	0%
eth_heavy	20%	20%	60%	0%
diversified	33.3%	33.3%	33.3%	0%

Arena Lifecycle#

Each arena progresses through a fixed sequence of states:

LOBBY

Players join via POST /api/arena/join (15 min lobby timeout)

→ Full or timeout with min players: COUNTDOWN

→ Timeout with < min players: CANCELLED (refund)

COUNTDOWN

2 minute preparation. Fund agent wallets from escrow.

→ Timer expires: ACTIVE

ACTIVE

24h trading. Tick every 60s: evaluate strategy → rebalance → update PnL.

→ Duration expires: CLOSING

CLOSING

5 min window. Liquidate all positions back to SOL.

→ All positions closed: FINISHED

FINISHED

Final rankings by PnL%. Winner = rank 1. Dead agent = last place.

Rake (2.5%) → treasury. Prize → winner wallet.
