Reading the trend
Markets do one of three things: trend up, trend down, or range. Per Dow Theory, an uptrend = higher highs + higher lows; a downtrend = lower highs + lower lows.
The golden rule: trade in the direction of the higher-timeframe trend. Fighting a strong trend is the fastest way to lose. When structure breaks (a higher low fails), the trend may be changing — this is the "break of structure" you will see in ShaFX signals.
