Thanks so much for all the calm and measured advice, it is fresh air compared to many of the crypto "voices"! I have been implementing your advice with some success, but wanted to share the "one that got away" today.
40% move, my buy was set just a little too low - i used the previous drops as a guide (white dashed lines).
Is it better to get in stages on the way down to avoid this in future or are these just things that happen :)
