The Power of Price Spikes On Intraday Charts

Last week ended on a very positive note for those who follow and trade filtered price spikes.
What is a filtered price spike? In short, I scan pre-market, and post-market trading hours’ price charts of SPY, QQQ, IWM, GLD, and GDX for a very special odd tick in the market which creates a spike on the chart.
These spikes could be to the upside or downside, does not matter. What they tell me is the direction which the market (market makers) are going to try and move the market in then next 48 hours.
