Not allowed. We do not support strategies that depend on execution speed or tiny price movements.
Positions must stay open at least 3 minutes (30 seconds with the Scalping add-on).
Even above that time, we flag micro-scalping: very many trades with tiny targets, near-identical repeated entries, large size for minimal gains, or behaviour that looks automated.
These patterns exploit the simulated environment rather than show skill. See "Minimum holding time and the scalp limit" for the exact thresholds.
