Google: preparing for sell signal

The price of GOOG has begun to move up and I am drawing a trendline to see the sell signal when it comes.

Bought Swatch

I have been watching Swatch (UHR) at Virt-x for the past few days. Yesterday's close gave a buy signal and I gave given an order to buy UHR at the open today.

The buy order gets executed at CHF 365.00

Bought Holcim

Yesterdays close for Holcim (HOLN) gave the buy signal I had been waiting for but I forgot to give the order to buy at the open today. Therefore, I bought Hocim now, at CHF 119.30

Holcim: will it give a buy signal today?

I wonder how Holcim (HOLN) will do today. Based on my chart, if it closes above CHF 117 today I should give an order to buy it at the open tomorrow, but is this really the turnaround?

Deciding against Holcim today

I see that the estimated opening price of Holcim (HOLN) has dropped to CHF 127 and therefore cancel my limit buy order, as I will be not at the computer at the opening to watch it.

Analysing Holcim

I have been watching the trend of Holcim (HOLN) for some days now and finally see a buy signal in yesterday's close. I plan to watch it at the open and hope to buy it on Virt-x at maximum CHF 129.

Evaluating Roche GS

If it weren't for the high fees charged by Swiss brokers, plus taxes, I would have sold ROG at the sell signal (at CHF 219.20 on 9 July) and bought them back at the buy signal (at CHF 213.00 on 31 July). For example, Swissquote currently charges a commission from CHF 9 to CHF 250 each for purchase and sale, depending on the amount of the transaction. Their current commission schedule is shown on the left (click to enlarge). On top of this come 0.075% federal tax and a stock market fee of CHF 0.10 per CHF 1000 transaction value.

Doing the exact calculation now, I see that a sale and repurchase would still have been worth my while, giving me a net profit of 0.7%
