A safe way to increase or decrease your risk parameters is to keep within +/- 200% of your average or deviation by a factor of 2.
Two main KPI we use here are trades and lot size. Each week, we will take an average of the mentioned KPIs and place a ceiling (avg x 2) and floor (avg / 2) for the trades.
Any trades outside these parameters will raise a flag on an account and be a possible violation.
