Here is the fix to a trendline break on the 15 min chart, yesterday SP 500 end of the day trade.
If your scalping you need to go to the 3 min possible the 5 min and look for a close on the last 2 bar to be on the lower end of the bar, if you like longer term use the 5 min .
This will confirm a direction on the trade!
If the trendline break on the 15 min chart show a close in the middle after it break the trend line wait for two lower closes on the candle to avoid premature entry.
Tha same thing applies to breaking the trend line up, close at the upper part of the 2 candle enter at the break out of the second candle.
This is a filter system to get you out of sucker trades.
Or run for the Gold ant the end of the day!
