What is trader churn? Trader churn is the rate at which active traders stop trading and leave a platform permanently. ~75% of retail traders quit within 90 days, costing institutions $200 to $2,000 per lost trader in destroyed acquisition cost, on our working range. Churn shows up as a marketing metric after the trader has gone; Discentra watches the trading behaviour that can come before it.
In the context of financial institutions, churn refers to the rate at which active traders stop trading and leave a platform permanently. ~75% of retail traders quit within their first 90 days. For brokerages and prop firms, each departing trader represents $200 to $2,000 in destroyed customer acquisition cost on our working range, depending on the channel and geography.
A firm can ask who owns churn in its own business: if the answer is marketing, the tools will be marketing tools, such as re-engagement emails, promotions and reduced spreads. Those address the operational side; they do not reach the trader who lost money in a way that felt uncontrollable and left after repeated losses with no support.
Churn is measured as a marketing metric, but its behavioural side starts earlier. Behaviours such as revenge trading episodes, tilt clusters, increasing position sizes after losses and shorter sessions can show up days or weeks before the trader stops logging in. Whether they predict churn in a given book is something a firm can test in its own data. By the time the churn rate moves, the traders are already gone.
Discentra is built to act on the behavioural side of churn during the emotional moments behind it, not after the trader has decided to leave. Our working window is the first few minutes after a trigger, an operational construct rather than a measured figure. A firm can measure its own current response time, from trigger to first contact. Coaching, not financial advice.
Why It Matters
On our working assumption, trader lifetime value runs $1,200 to $3,500 a year. A firm can size the loss from its own numbers: traders lost in the first quarter, times its own acquisition cost.
For prop firms, brokers, and crypto exchanges, churn reduction has a direct and measurable impact on unit economics. A 10-point improvement in 90-day retention applies to every acquisition cohort, so its effect adds up over time. Our bet is that the firms that solve trader retention will be the ones that cut the time to a response from days to seconds, not the ones with the tightest spreads or the biggest marketing budgets.
Frequently asked questions
What is trader churn?
Trader churn is the rate at which active traders stop trading and leave a platform permanently. ~75% of retail traders quit within 90 days.

How much does trader churn cost a firm?
Each departing trader represents $200 to $2,000 in destroyed customer acquisition cost on our working range, depending on channel and geography. On our working assumption, trader lifetime value runs $1,200 to $3,500 a year. A firm can size the loss from its own numbers: traders lost in the first quarter, times its own acquisition cost.
Why do traders churn?
For several reasons. Some leave over the platform, payouts or spreads. Others leave after losing money in a way that felt uncontrollable, with no support when it happened. That behavioural side can show early: revenge trading, tilt clusters and rising position sizes after losses are things a firm can look for in the weeks before a trader stops logging in.
Why does trader churn persist despite better platforms and education?
Part of our answer is timing. Discentra's rules look at the minutes after a loss, the window we design for, while a response built on re-engagement emails, promotions and tighter spreads plays out over days. By the time the churn rate moves, the traders are already gone.
