I thought you said that entry was at least as important as exit and were amused at VT's suggestion exit was relatively more important. My misunderstanding of your position.
Entry and exit aren't the mirror of each other, philosophically or otherwise. If you are a trend follower, then one trend ending does not necessarily mean it will reverse and form an opposite trend for instance. It may do nothing for a period then either continue or reverse. Dollar/Euro for the last 6 months is a good example. In your example you have an (arbitrary as far as I can tell) exit target of 370p. That wouldn't necessarily be a good entry point if reached. I'm not even sure how you arrive at such a target based on fundamentals. Totally beyond me i'm afraid.
I think you did misunderstand my position... you employ trend-following, whereas I've decided that this idea should not be my principle guide.
My exit point at 370 was derived from the observation that ITV (a company deriving its income from advertising) had already lost 40% from its peek - and, I argued, that Google's revenue streams would be similarly affected by reduced marketing budgets. I considered that Google (while significantly cooler than ITV) showed remarkable similarity to companies I'd read about declining in Japan after their 1990 experience - i.e. those with large P/E ratios who could seemingly raise arbitrarily large sums by selling shares... which suffered dramatically. 370p for Google is 40% off its peek... quite possibly not the best place to sell, but the only indicator I have. The time scale was more arbitrary... I picked six months as that would take us to January - where, I suspect, Christmas will favour other online companies more than Google.
Entry and exit are duals... but not in the way you assume I meant. The duality is this: at entry I deem the risk/reward balance to favour shorting Google to holding that sum as cash; at exit I deem the risk/reward balance to favour holding cash to shorting Google. The things which would make me re-assess my position are time (should Google not have fallen to 370 by mid Jan 2009) or news of a very significant nature about likely future revenues or further developments with the price of advertising and/or technology companies that allow me to refine my earlier prediction.

You've mentioned that entry for you is at least as important as exit, and yet appear to have made an entry at a totally arbitrary price as well, based solely on an expectation it will fall over 6 months. Your stop at 10% above entry is also arbitrary. i.e. not based upon volatility, price history etc etc. So, unless I'm mistaken entry, stops and exit are all arbitrary. i.e. Disconnected to the market which sets the price. I think that is an odd strategy.
The entry question is not so much a question of current value, but - rather - estimated fall remaining. Entry is determined based upon expected behaviour from today's absolute price. My stop at 10% above, however, you're right, is rather arbitrary - but not without some deduction. The worst case scenario to best case scenario is roughly 1:2 - this relates to my expected reward for success relative to risk. It is a measure of my confidence in my fundamental understanding of Google... there is no verifiable mathematics behind it. I like the idea of Google as it is a large company - I doubt I'll see a takeover bid, for example, even with falling share price... this, in my view, also takes the pressure off picking a tight stop... as I think it unlikely that the price would rise even 5% from the price at which I sold for any significant period.

Gearing is entirely personal. I wouldn't be comfortable with 10x leverage on an individual share. But if the total loss is £50 I guess you'll live. Would you do it if your stake was £500? £5000? £50000?
Absolutely, I'd do it. The stake is only relevant if I think it might move the market. What matters to me is my risk relative to my invested position. I assumed £10,000 in monopoly money with £500 to stake on high risk, high reward, positions... 95% cash and 5% speculative. My stake would be £500, £5000 or £50,000 if I were managing £100,000 ; £1m or £10m respectively... I'm shorting with Monopoly money, remember?

I'd aim to double my speculative stake on an annual basis - and, because the speculative stake is only a small proportion of my capital, I can afford to behave in an entirely risk-neutral way.

Paper trading may have its place, although I don't think it teaches you anything of much value. In fact, probably just about the worst outcome for you in the long-term would be if google falls to 370p in the next 6 months because you will think your strategy was successful, and will be tempted to replicate it with possibly larger real money sums. Much more useful to you would be for you to be wrong and understand how you deal with that outcome. I don't say this to be mean, but you would certainly learn more. Especially about leverage, stops, exits and price. You are pleased to be up 39% in a week, which is indicative of this since that is based on a 3% move in the stock. That sort of leverage will give you such movements de facto, but imo they are far too high to be sustainable for any long-term strategy.
I have significant uncertainty about the strategy - but (and I hope you don't consider me arrogant here) I will not be suckered in by success on paper. Each trade is entirely independent... and, in any case, Google is my best idea - and, as it falls in value, my certainty diminishes that shorting Google would be a good new play. If my on-paper short fails, but - in the mean time I establish better how to assess the fundamental risks - that would definitely tempt me to try again with real money. I'm about 80% sure my view is accurate - but only about 20% sure I'm exploiting my view the right way.
I'm pleased to be up initially - since, I consider, that is the most likely time at which I could be forced from by position as a consequence of the capital I've allocated. I recognise that this initial success is almost entirely luck.
Still with monopoly money, I'm considering shorting Apple. My reasons are that it has a huge market cap; high P/E ratio - and targets an affluent consumer. Its share price has been doing far better than Sony, but I do not see a substantially better business proposition... I also suspect that apple consumers might be getting tired of reliability issues with Apple's products which historically sold on a presumption of exceptional quality... but, today, anecdotally, are being returned or breaking just out of warranty more frequently than in the past. Sony has fallen 35% from a peek, Apple's price is now 156 - its peek was 202 - making a target price of 120 plausible within six months. Apple has more diversified revenue streams than Google - and has a habit of being better able to create hype. I believe that the probability is greater than 50% that Apple's share price will slide... I think I might benefit here from either a very tight stop (to minimise my loss) or less leverage - maybe both... but I think Apple would still work with the Google strategy. With a 1:2 worst:best case scenario weighting, that suggests a stop-loss at 178 - at £2.22 per point. I estimate the odds of this Apple short are 25% worst case scenario; 25% best case; 50% near break-even. Conversely, I could buy options with a January strike of 170 for 25.6 each... the returns are significantly smaller (as the drop in price I'm expecting is smaller) but this does mean I could hold onto the position through a rally.
(It would be really handy if there were a system to manage this monopoly money portfolio.)
