Yes, that's correct. You would have made this much of profits had you started to accumulate gold somewhere in early September 2018 till now. US$1000 invested back then would yield you US$1400 now.
From the chart, you can see the real spike begins in May till Sept 2019. Then it went into consolidation or hibernation for 3 months till Dec 2019 before it picks up momentum again. Of course, the uncertainty surrounding the US Iran matter and also a weakening dollar helps to drive the gold price up.
It has been up for the last 10 days and it would be healthy for a minor correction before the bull charge higher up again. If you are in profits already, take some if you like, adjust your SL and prepare to buy in again when there is a pull back. I am hoping it will come back to 1542 level as a correction so that I can buy more gold at cheaper price.
Remember, just because an asset goes up, it does not mean it will continue to go up higher. Make sure you have a clear strategy to use, adequate SL and capital management.
Trade safely.
