Quote from NZDSPeCIALISt:
It creates a dangerous precedent.
IMHO 100 trades should take 3-5 months not a few days/weeks (as it sounds like from the tone of your post), because the training session you advocate will be continued on in the trading arena. If someone is clicking 20 times one day (because they are in "training") it will be hard to click just once or twice when the "training" has ended.
The number of trades is relative to the time frame and style of the trader. The 100 trades in 3-5 months that you describe sounds like a not very active swing trader, while 20 clicks a day is a moderate daytrader. For anyone though, repetition is a good way to learn.
