Yes I do understand how high frequency trading works.

Glad to hear it.
Since BitStamp (and BitFinex, and all other known bitcoin exchanges) don't offer high frequency trading, the rest of your post is off-topic and irrelevant to this thread.
Meanwhile, the bitcoin exchanges (which are on-topic and relevant to this thread) are all able to engage in their own "insider trading" before the order book is updated. Proper regulations and good audit practices from trusted third parties can significantly reduce the incentives and likelihood of exchanges engaging in such conduct.
It is difficult if not impossible to provide hard evidence of deliberate insider trading misconduct at bitcoin exchanges. That is not to say that there are no obvious signs that it is happening (at Bitfinex and some of the other large exchanges). I trade on more than 10 different exchanges and track "slippage" on each trade. Slippage occurs when trades are not executed as expected for one reason or another. I don't dwell too much on why it is happening and just respond to it by "penalizing" exchanges with significant execution slippage and re-route orders to other exchanges.
Sure. We trade mostly on a subset of the following:
Bitstamp
Bitfinex
ANX
LakeBTC
Kraken
BTC-China
BTC-e
Cryptsy
Ok Coin
Coinsetter
I am debating putting together a more in-depth analysis on trade execution. If you are interested follow @ https://twitter.com/LiquidXCoin or sign-up at liquidX.io
Whats your opinion on Poloniex? I've moved everything there for my occasional altcoin daytrading, im paranoid about exchanges dissapearing these days, im not sure what to do, im starting to think i should put all on my local wallet but i want to daytrade.
I can't really say anything negative about Poloniex from a user experience standpoint. The trade execution is quite good - definitely better than cryptsy. Support at Poloniex has also been responsive and competent when I contacted them. I wouldn't recommend storing large balances on any exchange.
