Start with the downside
Consider the loss you could bear before choosing the size of a position. Examine an ordinary adverse move and a larger gap or liquidity shock, including financing and conversion effects. A stop order can support an exit plan, but its trigger is not always a guaranteed fill price. Diversifying exposures may reduce concentration, while correlated positions can still lose together when market conditions change sharply.
Keep the controls realistic
Review how total exposure, available collateral and open orders interact rather than evaluating each trade in isolation. Avoid increasing risk solely to recover an earlier loss. Product protections must be read in the actual agreement and may differ by entity or jurisdiction. FYLU has not established live risk controls, loss limits or negative-balance protection; its education and preview do not make a customer's capital safe or cap a possible loss.
