We typically encourage traders to limit risk to a maximum of 1-1.5% per trade idea to support healthy risk management habits. This is not a robust rule for Phase 1 and Phase 2 accounts, but risking a significant part of your Maximum Daily Loss on one idea can suggest that the strategy may not be well-tested or that conviction in the setup is lower.
For Funded Legacy accounts, to avoid uncertainty and ambiguity, a risk limit of 1.5% per trade idea is a strict rule.
Trades are treated as one trade idea when they are opened on the same instrument, in the same direction, and within 15 minutes of the previous trade being closed.
