Summary
Add two per-user metrics: the average time to complete an order (from taken to SUCCESS) and the completion rate (percentage of taken orders that reached SUCCESS). Both are stored on the User model and displayed in the public channel alongside the order.
Motivation
When two sellers (or buyers) offer identical terms, there is no way to distinguish them by reliability or speed. A visible completion time and completion rate give users meaningful signals to pick the better counterparty, improving overall trade quality and velocity on the platform.
Proposed UX
Order listing in the channel would include two new lines:
⚡ Sell 100,000 sats
💵 1,000 USD — Bank transfer
👤 @alice ⏱ avg. completion: 12 min ✅ 89% completion rate
If the user has fewer than 5 completed orders:
Data Model Changes
New fields added to the User model:
avg_completion_time — average time in seconds from order taken to SUCCESStotal_taken_orders — total number of orders the user has taken, used as the completion rate denominator
The existing trades_completed field is reused as the completion rate numerator.
Calculation Logic
Completion rate — recalculated on every SUCCESS transition:
completionRate = (trades_completed / total_taken_orders) * 100
Average completion time — updated on every SUCCESS transition using a running average, where elapsed time is measured from order.taken_at to the moment the order completes.
Display Logic
trades_completed >= 5 → show both metrics alongside the order in the channeltrades_completed < 5 → show new trader or omit both metrics entirely
Localization
New keys needed in all locales/ files:
avg_completion_time — e.g. "⏱ avg. completion: {{time}} min"completion_rate — e.g. "✅ {{rate}}% completion rate"new_trader — e.g. "⏱ new trader"
