My question is: when you move the stoploss level, do you consider the level that the SMA30w/SMA10w had at the moment of the low or the level that it has when you move the stoploss ? And, to go further in this idea, do you eventually move the stoploss following the SMA, provided that the stoploss stays under the last low ?

I'm sure its covered on page 184/185. You should move your stop when its making its way back up to the last high, and you should move your stop loss at the point the MA is below the low, not the level of the MA at the point you move it.
You also only trail the stop loss after the next retracement and then next continuation. You don't trail the MA
hope this helps
