I have tried various techniques. My latest approach is using BUYING POWER and buttons like below.
I am liking this so far. I am a momentum trader mostly - so I have to make quick decisions and all the risk/reward calculations etc was too much to handle.
Not many people are going to like my approach
I guess you have find your own technique.
B 200 -> buy 200 shares
B .20 BP -> buy 20% of buying power
S SL 25c - > (set for shorts) stop loss 25c above the price
S SL $150 -> (set for shorts) stop loss to fixed $150 total above the price based on the total price and quantity of of the shares
I guess you will be able to figure out the rest.
