Strategy flexibility – Can they build for your specific approach (arbitrage, grid, market-making, scalping) or do they only offer one template?

Exchange API security – The bot needs secure API key handling, encryption, and 2FA so your funds aren't exposed.

Backtesting environment – A good dev team lets you test the strategy on historical data before going live.

Multi-exchange support – Bots that only work on one exchange limit you long-term.

Ongoing support – Markets change, so the bot's logic often needs tuning post-launch.

For reference on what a full-scope build looks like, Dappfort's crypto trading bot development services cover most of these spot/futures bots, arbitrage, AI-driven strategies, and white-label options if you want to launch under your own brand.
