Quote from themickey:
I've been using Amibroker for over 10 years and SierraCharts for about 2 years.
For stocks or mulitple symbols, AB is light years ahead of SC for speed and number crunching, backtesting and maintaining a database of historical data.
However I no longer trade stocks, I just trade one futures symbol - SPI, so I don't require the grunt and capabilities of AB.
These days I use AB to maintain many years of historical data which helps me see the big picture, as well, I do make suggestions to a friend on which stocks to buy. I can backtest hundred of symbols simultaneously (I screen for long term volatility looking at a number of parameters) and can come up with a result in a minute therabouts
I use SierraCharts as my trading platform linked in with InteractiveBrokers, I think SC is better for this than AB.
With SierraCharts I can design whatever entry/exit/stop/scalp system I like for placing trades and it is very easy to program and link in with IB.
So to summarise, AB is great for programming and testing for multiple suitable stocks, SC is great for placing trades to my preferred methods.
