Totally agree. Whatever I read at ET I tried them out. Most did not work for me but I did find some very very good advices, like yours here, that made me a much better trader.
To those interested, here are some of my lessons learned: As an amateur retail option trader, I could not trade complicated instruments (e.g., complex combinations), compete trading indices, compete trading volume and be profitable... As a small trader, I needed to keep things simple, to make directional bets vs hedging, delta neutral, volatility.... As a small retail trader, I was unable to day trade options profitably, the MM and professionals killed me with bid/ask and.... As a small retail trader, I needed to get my entry right to be profitable.....
But in spite of all that, I think a small amateur option trader can make a good living.
I appreciate the coaching and enjoyed reading your comments.
Regards,
I don't know why you can't daytrade AAPL stock options..last time I looked at near ATM strikes intraday, the spread was only a couple cent?
There are only a handful that have these tight spreads though..most stock options are not very good for fast trades..but can be OK for several hours holding if you get your timing right.
Options are a different ball game to daytrading stocks..but can be very useful on ES if you wait for the low risk setups..I find the model price handy for a quick guide if the price has gone way off with volatility changing..if the last price is way above the model price..I will not be buying

Thing I found with options is that it requires a lot of time to keep on top of trades..adjusting strikes when required..much prefer the simple in and out based on underlying move..you either win..or loose..better you get the less you lose..the less you lose..the better the chances of winning!
