    Backtesting time period

    One of the biggest threats to successful optimization/backtesting is the possibility that the results are just a curve-fit (or "over-fit", if you use that instead …) i.e. they are just the strategy settings that would have worked best by chance over the historical data used, but contain no...

    Technical Analysts-- Are Gaps Really The Best TA Pattern?

    Explain liqudiity. How are prices supported and moved based on Supply/Demand?

    I am wading my way through TradeLink source code (from TradeLink.org) for a Project. The TradeLink.AppKit namespace requires referencing the assembly SeasideResearch.LibCurlNet . I have not succeeded in finding this using Google. Anyone know where to get it? Thanks.

    Backtesting time period

    Sorry, I didn’t give you an answer for how many trades a backtest should have at a minimum! [I am reading the following data from statistical tables calculated for Normal Distributions, which should be fine for large populations where the Central Limit Theorem can be assumed to apply.]...
