Confuse about leverage things

lets think i have 500 Rupee and i took a leverage of 30x on it and taken a short trade and i saw the next candel closes 5 to 6 point time down and that give profit of 100 rupee and i did it multiple times. Is that legal that taking leverage in market and exiting from a market just in two minutes???

Yes, it is legal. But I can’t think of any instrument in NSE/BSE which provides 30x leverage.
