Sorry to hear about your Internet bubble story, but truth be told we all get into those phases. That's why risk management and position size is so critical when trading and investing. But it does sound like you were on the right track with MEOH, so that's something to think about... :)
Regarding the chart, 5m = 5 minute chart, though it only prints if activity actually took place during that 5 minute period (or 1 minute period for a 1m chart, etc). Regarding increase in volatility, I wasn't talking about indicators, simply the underlying price action as shown here:
What you see there are people buying high offers and low bids with not much going off inbetween, until "out of the blue" it tanked. Think of it as a bit of "hot potato". Finally people just gave up, or placed stops just below that range, and when it broke, everyone piles in all at once and chases it all the way down.
Thanks for your helpful explanation. I am surprised at the spreads between the highs and lows. I didn't realize there was a $.10 range in price, otherwise I might have tried to lowball when I bought Steem. Or highball when I sold SBD...
