The order of operations most people get backwards

Leverage is an output, not an input. You decide how much of the account you are willing to lose on this trade, you decide where the idea is wrong, and those two numbers determine the position. Picking leverage first and discovering your risk afterwards is how accounts end.

risk_amount     = equity x risk_per_trade
stop_distance   = |entry - stop| / entry
position_size   = risk_amount / stop_distance
margin_required = position_size / leverage

What the leverage check is telling you

If the position that fits your risk needs more leverage than you have, the answer is a wider stop or a smaller risk budget — not more leverage. And if the required position is tiny, that is information too: the stop is far away, meaning the idea is low-conviction at this price.
