For smoothness, there are three main conditions left (Break-Even, ATR Trailing, Step Trailing):

Enable ATR-based trailing stop = true;

Enable break-even  = true;

Enable step-based trailing = true;

Enable multi-level trailing = false;

Enable safety SL  = false;

Because:

Break-Even (Item 1): Keep it first because it's basic protection (move SL to break-even + lock a little). It's not too aggressive, helps prevent losses, but doesn't cap profits significantly.

ATR Trailing (Item 2): Keep it because it's adaptive to volatility (using ATR * multiplier). A wide ATR provides more room for profit runs, which is good for volatile markets.

Step Trailing (Item 3): Keep it because it locks stepwise (not immediately tight, but waits for the step to be full), allowing profit runs between steps longer than real-time trailing.
