Excellent example. And by the way all questions are good questions, it is the only way to learn.
Let’s take a look at your example.
The last trend change was on Oct 16, 2019 when the trend turned positive.
Entry 1.28299 (call it 1.283)
The lowest price from the previous move of the trend was on Sept 3, 2019 at a price of 1.19586
871 pips SL
1st order take profit = 1,742 pips
2nd order take profit = 3,484 pips
3rd order exit on next zero line cross
Seems extreme. But in three weeks price had moved over 1,000 pips. Which means volatility is HIGH.
Our position sizes will reflect that volatility and be small because of it.
Do I think we will move up 2000 pips for a full take profit on order 1?
Maybe. If I have learned anything in 19 years of trading is that the unexpected happens.
Is it possible we trade down 871 pips to a full stop out and los -1.8%?
Maybe, but I doubt it.
What is most likely in this case, which is abnormal, is that we get a zero line cross exit either in profit or at a loss and taking either a small gain or a loss and move into to the next trade.
That is the brilliance of the strategy. It is factoring in all types of market moves no matter how they occur.
