Im new at technical analysis and even though i have read alot of stuff about it i still dont understand some things , all i see people using are indicators like moving average and oscillators etc , i have yet to see anyone use a basic trendline analysis or price patterns as the core strategy , i also notice that its really hard to code those in order to backtest them , no backtesting software includes code for these strategies , whats the purpose of these things? cant you use them as stand alone strategies?
