3.6 Limitations and Gotchas

Be clear about what Capture Terminal cannot do for you:

• No guarantee of fillability

  • Engine looks at quotes, not your final execution path.

  • Depth can be thin; your actual fills may be worse.

• No MEV protection at this layer

  • If you just broadcast your transaction via public RPC with obvious routes, you can get frontrun or sandwiched.

  • MEV-aware logic belongs in the execution layer (your bot or Capture Bot).

• Latency is still your problem

  • Feed can be fast; your wallet / infra may not.

  • If your end-to-end time is slow, you’ll often arrive after the spread closed.

• Estimates, not omniscience

  • Net profit is based on assumptions about fees and slippage.

  • Reality can diverge, especially in volatile conditions.

If you expect Capture Terminal to magically print free riskless trades, you’re delusional. If you use it as a high-quality radar to spot and quantify edges in real time, it’s doing its job.
