Strategy: Remain 5 mins

Binary: main_remain_5_mins (default)

Buy a token (BTC/ETH/SOL/XRP Up or Down, from config) when:

• Its BID price is between trigger_price (default $0.90) and max_buy_price (default $0.95)
• At least min_elapsed_minutes (default 10) have passed in the 15‑minute window
• At least min_time_remaining_seconds (default 300 = 5 minutes) remain before market close

Order size is controlled by trading.fixed_trade_amount. The bot does not buy if remaining time is below min_time_remaining_seconds.

Config (summary):

Field	Default	Description
trading.trigger_price	0.9	Minimum BID to trigger a buy
trading.max_buy_price	0.95	Maximum price to pay (skip if above)
trading.min_elapsed_minutes	10	Minutes that must have elapsed
trading.min_time_remaining_seconds	300	Minimum seconds left (5 min)
trading.fixed_trade_amount	—	USD per order
trading.enable_btc_trading	true	Trade BTC markets
trading.enable_eth_trading	etc.	ETH, SOL, XRP from config

Risk: If the outcome loses, you can lose the full position size. Use small fixed_trade_amount and run with --simulation first.
