Perhaps its obvious but I guess there are several bots doing arbitrage between mtgox and tradehill, if so shoudn't be tradehill leading the price fluctuations because of the smaller market? Meaning that buying 100 btc in TH rises the price higher that in Mtgox.

Ok i guess i'm wrong, please clarify. I'm asking this because I think that if someone would want to represent in a buying strategy an upward trend, he might try it on the smaller market right?

This is only a guess, but I think that in the case of automated fast-acting arbitrage between two exchanges, one large and fast moving; and one small and slow then the result would not be price lags, but rather larger spreads on the smaller exchange.

If the bids on the large exchange increase past the asks on the smaller exchange then the bot can buy cheaply on the smaller exchange and sell at a profit on the larger exchange.  That will cause the ask depth on the small exchange to be eaten up until profit is no longer possible.  Being smaller and slower, it will take longer for bid depth on the small exchange to build up under that new minimum ask.  Hence, the spread will be bigger.

The opposite is also true of course when the price falls on the large exchange such that the asks are lower than the small exchange's bids.

So you would confirm that making a big buy in TH exchange would rise the price in the MTgox giving the Bid in TH will soon be higher than the ask of MT but then the bot will pay the ask in MT and sell at the higher bid price in TH resulting on a clearer upward trend than the one doable with the same cash amount in MT. Of course the amount to buy at a lower ask price in MT might be enough as to lower inmediately the price in TH. But when would this kind of strategy be usefull?

This is usually the case.

I'd add that the larger exchange will always lead the price change for two reasons:
1. they have a higher trade volume (more liquidity)
2. spreads are lower (which means better prices all round)

As you can see both reasons self-reinforce each other. Ie. the lower the spreads, the more reason people would want to trade there; the more people trade there, the lower the spreads will be.

Which leads on nicely to the next question:

So you would confirm that making a big buy in TH exchange would rise the price in the MTgox giving the Bid in TH will soon be higher than the ask of MT but then the bot will pay the ask in MT and sell at the higher bid price in TH resulting on a clearer upward trend than the one doable with the same cash amount in MT. Of course the amount to buy at a lower ask price in MT might be enough as to lower inmediately the price in TH. But when would this kind of strategy be usefull?

Yes, thats right, if somebody placed a large buy (or sell for that matter) on TH, then TH will lead the price movement, however why would somebody place a large buy order on a less liquid exchange when the price is worse?

It does happen occasionally, in which case, anybody who actively watches BTC prices closely or those who arb will have some very easy profit. This will have the affect of adjusting the market prices accordingly, in the way that you mentioned.

When would this kind of strategy be useful? Well either to arbitrage, or if you know the order is large enough to move the prices on the lagging exchange (MtGox in your example), then you can pre-empt the price movement... maybe if you combine it with a geared order from bitcoinica then profits to you!

You def. have the right idea in profiting from arbitrage. That's why I believe in this ICO bc they are aiming to make crypto easier to enter for all with their novice friendly UI and the first ever arbitrage exchange that will allow for less market volatility which keeps so many inexperienced and afraid people on the sidelines. Arbitrage with a legit company will provide a greater opportunity to profit in this economy.

I've found that exact trading strategy discussed on http://cryptocurrencyarbitrage.net/day-trading-cryptocurrency/
Basically if you are a day trader it makes sense to find a way to already start you trade in a profit.
For example if Ethereum is trading at $500 on exchange #1 and trading at $550 on exchange #2 then you can just buy on exchange #1, transfer to exchange #2 and either take the profits immediately or use the 10% as a buffer for a winning trade.
That way you have the ability to set a stop loss at $525 and if you get hit you are still in profit.
If you don't get hit then you can watch you trade multiply without the stress of it dipping under your initial investment.
The strategy is discussed in more detail on the site above
