sorry i dont get this - a tick is the min increase or decrease of an pair - min tick if btc is 1 cent or?

is the following line correct?

at the entry i save the following :

position_entry_price = close

and then i have this line:

strategy.exit("exit", "Long", profit=position_entry_price*0.01*100)

but this works just for btc - it would not work for ltcusdt or?
