Question 1

How much leverage can I safely use?

Accepted Answer

Enough that a realistic adverse move never reaches your liquidation price. Liquidation happens near a 1/leverage move against you (adjusted for maintenance margin), so if you expect swings of 20%, leverage much above ~4x leaves no room. Always size leverage to the volatility you actually face, plus a buffer.

Question 2

Why add a safety buffer?

Accepted Answer

Because liquidation is not the same as your stop — you want to be stopped out or exit well before the exchange force-closes you at the worst price. A 20-30% buffer keeps the liquidation price far enough away that a normal spike or wick does not trigger it. Tighter buffers mean cheaper mistakes become fatal.
