There are no restrictions on trading style and the actual trading strategy you choose during the demo evaluation is completely up to you. However, certain strategies are prohibited as they go against our terms of use policy due to them being deemed as "cheating". Note that any strategy that takes advantage of demo environment will result in the closure of a trader’s account, whether in the evaluation phase or while funded.
Below are some, not limited, examples of prohibited strategies:
Guaranteed limit orders
Data feed manipulation
Trading on delayed charts
Grid Trading
Macroeconomic trading during high impact reports and being filled at an unrealistic price due to the volatility.
Martingale
Hedging between accounts
Tick scalping
Signal trading
Reverse arbitrage
Account management
Latency arbitrage
High-frequency trading
