What is wiggling? Wiggling is constantly monitoring a position, and getting in and out of a trade ultra short term if the direction longer term is still valid.
Nvidia (NVDA) is a perfect example. Longer term, on a daily chart, the
stock is finally oversold. Every time this stock has been this oversold it
has a strong rally. The problem is that one doesn't know where it is going
to stop going lower. So longer term, you think it's going up, but short
term you don't want to get hurt buying too early.
The key is the "wiggle". A shorter-term chart, the 15 minute, has worked great for spotting short term buy and sell triggers. But a 15-minute stop order leaves a lot of points "on the table".
The key in "wiggling" is as long as the 15-minute chart is in an uptrend, then every ATR trailing stop buy signal on a 1-minute can be taken. In an uptrend, usually the stopped-out losses are very small, compared to the gains when right!
