A spring bar for example anywhere else but at support is just another bar, it has to be used in the correct conditions for the bar in question to have meaning

This process takes time and effort. It's of benefit to go through the charts, build a story of strength or weakness. Look for immediate strength then look for test bars. Used on a daily time frame, this trade is very powerful. Test bars are left for the whole day with no professional involvement, it gives horrible flat trading for the intraday, BUT of huge significance to the large operators. Thinking in multiple time frames is a key to fully understanding the cyclical nature of the markets.
