Live market scanner

how can i use scanner in live market for the following conditions?

  1. in 30min chart bullish engulfing pattern.
  2. in 30min chart crossover of 20 sma from below/above ?

basically how can i filter stocks in live market in any time frame for some special conditions/Patterns
like crossovers,bullish engulfing,evening star,hammer etc etc.or like MACD bullish divergence in any time frame(30min,4hr).

If its not possible in zerodha scanner please suggest if there is any other option available like any website.

As scanner works with LTP prices and the SET functions may not work so, all the chart patterns may not possible, you can try the codes available in Expert Advisors page from this Link
Also make sure you enter proper spaces between the tradescript in scanner
