BTC short-term contracts do not require switching between short and long positions so frequently; do not go against the trend. Just need to place limit orders at 117450, 116850/116666, 116350 (received at 116850, so catch less here), and 115750 in batches to catch low longs. Place 6% of your capital at each level with 50x leverage. A small defense at 115000 to reduce positions by 1/5 is sufficient. Whatever level you receive, take profit at 50% between 118800-119600, and after breaking through, take profit at 25% at 120750, keeping the remaining positions at breakeven. Small capital should avoid BTC contracts; the short-term contracts with the highest profit potential remain ETH and SOL.
