Manual input of lot size

Scalper joystick use karne mai bahot achha hai but thoda sa upgrade ki jarurat hai voh hai bade lot size lena ho to manually increase decrease karna padta hai uske direct lot size change kar sake for example 1 preset hota hai to jisko 10lot lena hai usko plus kar karke karna padta hai jo usme 1 ko direct 10,15,20,25… kar sake to bade lot vale trader use karna bahot aasan ho jayega plus karne mai time chala jata hai isiliye
