Sam,
Putting this up for your consideration- No concept of actually trading in that fast a time frame that you and the others here employ.
But as I compare your charts, 5 min and 1 min, I noticed you have ma's but You are watching price action on a fast time frame and reacting. On the last chart, you had pulled a long trend line through and mentioned exiting on break of the trend-
You may want to try some faster ema's..closer to price action.
In the chart those first bars that "weakened" on the 1 minute are but allowable noise I would think on a 5 minute. You have also mentioned taking profits too quickly, and missing some of the trade. Maybe some version of this would be useful.
Consider, once the trade is in profitable territory, and you have perhaps locked in some profit, step back with a portion of the trade using a higher time frame chart- 5 min, and follow price action on it. The price swings will be much larger and the stops will be necessarily so as well.
I annotated a 5 min chart with a 5 ma and a 5 ema- The 5 ma follows price action closely. What looks like weakness and says "EXIT-Lock in Profit" on a 1 minute chart looks like allowable noise on a 5 minute chart.
The premise is USE the ma's to your advantage, and if price momentum slows and price hits the ma or closes below it, raise the stop- but wait until the bar closes.
I guess you could look over some of your past trades and easily determine whether this would have proved beneficial or not, and the opportunity to have a larger win. I'm thinking 1/3.
Just some thoughts- SD
