Lua индикатор для Quik, Bollinger Bands %b Oscillator
Ищу Lua индикатор для Quik, Bollinger Bands %b (Bollinger Bands %BB Oscillator). На MT4 есть в открытом виде. Возможно у кого-то уже есть переделанный в lua. Буду очень признателен в помощи его отыскать. Если не найду, придется переписывать самому в lua...(
Кому интересно, переделал индикатор Bollinger Bands (ВВ.lua) под осциллятор Bollinger Bands %B
