hello.
i have some questions about binance futures i hope to understand.
1.what are those perpetuals ? why there is btcusd perpetual priced x and some price way up or low.why do i have to buy 100 $ for each "share".
2.when i do trailing command it doesn't do anything.i set the callback and price activation.put the % of how much to invest, click buy long or short and nothing happens.it doesnt show new open order.
thanks
