This is a good starting point for new people. However, you really should probably explain when people should buy on these indicators. All you do is explain what the technical analysis tools are. You never really explain when people should buy or sell using them. For instance, on Bollinger bands, if the candle is crossing the bottom line, it's probably a good time to buy and if a candle is crossing the top band, it's probably about to come down in price a little bit, so you should sell.
It is indeed a detailed articles on technical analysis he should have included how to spot those zones or areas where to buy or sell with those indicators probably he should have added some candlesticks patterns formed coupled with those indicators just like bollinger bands you mentioned which will signaled a short or long positions, overall its an eye opener for newbies in trading particularly how to spot those resistance and support zones.
