Watch: Thin at this size6.5 / 26.7 bp
At $10k entering HTX costs 26.7 bp, fee and slippage, 4.1× Popdex’s.
Note: Margin at max leverage$200 + $333
Popdex 50x, HTX 30x. Keep about 2× this so a sharp move doesn’t liquidate one leg.
Watch: Payment intervals differ1h / 4h
Payments land at different times. Close right after the slower leg pays.
