This indicator make a sound each time a new tick is deteccted

the value for the tick can be a new Ask, a new Bid or (Ask+Bid)/2 to ensure you never miss a tick

there are 16 sounds to choose from by default and you can also use your own sounds if you want
initially there was only one built-in sounds, which is a sheppard tone (a sound that continuously goes up or down seamlessly) but later I added 15 more sounds

This is very useful for manual tick scalping, as you'll know when price is going strongly in one direction

this is very useful for scalpers

The indicator has many more settings and shows a big "MUTE" button if you need to make it silent and everything is customizable (like size and position) !
