When the trendline is broken, wait for the first decision candle AFTER the candle that breaks the trendline.
Make sure this decision candle is large (not small) and the body of the candle is at least 75% of the candle (25% wick). The wick may touch the trendline, but the body of the candle cannot. Then enter at the close of this decision candle.
Place your stop 15 pips above the high (going short) or 10 pips below the low (going long).
Place your limits based on the fibs or support/resistance.
Never forget equity management! Do not risk more than 50 pips in a trade.
