Would you trust an online backtesting tool to build strategies ?

Amibroker ----> The world's fastest portfolio backtesting and optimization

Amazing speed comes together with sophisticated features like: advanced position sizing, scoring and ranking, rotational trading, custom metrics, custom backtesters, multiple-currency support

Well speed cannot be measured or compared and amazing is simply a nonsensical term really. And entire statement "Amazing speed ....currency support" start to finish is a stupid ass sales pump all over the web and represents no original thought or relevant contribution.

hey guys great notes! especially about the backtesting tools. We are not aiming to give an exact backtest which depend on exact order flow and mimic algo trading, more for bigger time frames, maybe starting from a minute and anything from there. mimicking milli second trading is very hard and not reliable at this point for us.
But it could work for day trading, swing, trend trading etc'

All your secret sauce, of course. But I'm being overly rude. For casual exploration of the data it may be a very good tool.

Even if you get security right, the biggest problem is investing time into something that might end up going offline.

I started using Quandl as a datafeed and knew it wouldn't last forever for free. Even knowing this though, when it stopped being an option it really sucked. I still wasted so many hours over adapting my programming to that particular data feed.

I loved Quantopian when it was around but knew that it was not going to last long term. I was just getting high quality data for free. Ultimately though, it still wasn't really worth the time in retrospect.
