I do not know what kind of technical charts or conditions you are talking about. I will only tell you what I do:
1. I am a client of Zerodha and use a facility called screener.smallcase.com for some screening criteria.
2. That however, is not enough for some specific strategies I need to use(like Triple EMA, or double EMA and MACD). For that purpose I use Python programming. But I can assure you that learning basic programming skill is not impossible(I am no IITian) to learn and use. The only reason for using Python is the large number of free APIs available(yes, absolutely free EOD data), unlike some paid software like Amibroker.
