I appreciate the nice comments, but I also have not mastered timing the dump and don't think anyone completely can (only the insiders really know, and sometimes promoters like APS will purposely shake out weak hands such as mine). True, I have not got caught in a crash in about a year; however, I more often than not sell too soon on a sign of weakness and the dump does not come. This is why my monthly trade counts are so high. I don't mind selling in the name of caution - for example, I literally sold SCRC about 10 times when it turned out I did not need to, but the last time, I did need to and missed the 50% crash. Sure, I made less money on the way up by selling and then re-purchasing, but the "Key" is to miss the crash and a large loss of capital. Trade when the up-trend is obvious and fairly safe - no need to hold an OTC ticker that is moving sideways during the day.
Don't worry about your trade count or missing runs - just avoid the crash at all costs. Most of these tickers pull their big moves from 9:30 - 10:15 and 3:15 - 4:00; as such, I often don't hold during the day when I already took a nice morning profit or can jump back in for an EOD run and possible morning gapup. Occasionally, a stock will dump EOD - ARTH nailed me with this last week - but one must take some risk. I prefer to invest large dollar amounts so that 5% gives me at least $500 and 10% gives me at least $1,000 - those are nice returns in one day and I have no need to risk large dollars all day when a crash may arise.
Every trades a winner, and every trades a loser, and the most you can hope for is to die in your sleep.
