Trading quantitative strategies focuses on managing unrealized gains and position sizes. This operational logic is simple but very practical:

First, open a position when the system signals, with the primary principle of protecting the principal. Once unrealized gains reach between 70% and 100%, reduce 30% of the position to lock in profits. This way, you preserve the opportunity for further upside while reducing the risk of drawdowns.

Next, be patient. Allow the remaining position to follow the moving breakeven point until a sell notification is received. At that point, sell 50% to 75% of the holdings, and let the remaining part continue to follow the breakeven line. This approach allows you to benefit from market rallies without being knocked out by minor adjustments.

The core idea is: reduce positions in batches, gradually lock in profits, keep risks manageable, and maintain flexibility in gains.
