TA'ing leveraged products

Leveraged products often "reset" overnight, and essentially track the underlying assets movement during market hours only. So if an underlying security pops 10% between close and open, the leveraged product gets priced that morning, against the open of the underlying asset. In theory, that movement wouldn't be captured by the leveraged product. At least that's how I understand it - for non-24x7 markets.

Note to self: don't fall into this trap again.
