Comparisons
Side-by-side comparisons for prediction-market bot developers.
- Binance only vs Multi-exchange median
Binance only vs multi-exchange median as price signal
Binance is faster and simpler; multi-exchange median is more robust. Chainlink RTDS uses a median. Here is why v4 follows the same approach.
- Build it yourself vs Buy from predtools
Build vs buy — prediction-market trading bot
Time investment, maintenance debt, and edge erosion: comparing building a Polymarket bot from scratch versus starting from predtools.
- FOK (taker) vs GTC (maker)
FOK vs GTC orders on Polymarket — taker vs maker
FOK fills immediately or cancels; GTC rests on the book until filled. The choice determines your fee side, fill certainty, and adverse-selection exposure.
- Maker strategy vs Taker strategy
Maker strategy vs taker strategy on Polymarket
Maker earns rebates but faces adverse selection. Taker pays fees but controls timing. A worked PnL example at $0.50 mid shows the real cost difference.
- Node 22 vs Bun
Node 22 vs Bun for trading bots
Bun is faster on startup and smaller on deps, but ecosystem compatibility with clob-client, ethers, and ws is the deciding factor. Node 22 wins for now.
- CLOB API vs Gamma API
Polymarket CLOB API vs Gamma API — what each one does
CLOB handles orderbook and trading; Gamma handles market discovery and metadata. Both are usually needed. Here is how they divide responsibilities.
