Hi This is my first post here. Would be glad if any advice could be given. I am trying to backtest a few major forex currency pairs. I am a newbie to backtesting except on MT4 platform which has its limitations. If one can choose the most accurate timeframe of data to test, it has to be tick data although it might not be practical for certain aspects. Requirements 1.Platform able to import and backtest 3rd party EOD tick data (not by interpolation from high TF of course) 2.Support portfolio testing and simultaneous money management 3.Non lease based, one time purchase, no requirements for RT data I have read through many forum reviews and posts, tested a few platforms 1.Tradestation Ver 8: Did not succeed in even importing ASCII file despite trying solutions i can find on the net. Also seems to be a general bias that platform is not as up to date with its competitors. 2.AMIbroker Tried out the demo, had an email reply too from them that it can support tick data backtest on full version,by adding an AFL code to do so in the default format file. (can anyone concur that this can import and backtest tick data granularity?) 3.NinjaTrader Did not try out demo, read about its limitations and also issues about the market replay mode 4.Forex tester Ver 2.5 Apparently does not support tick data, new ver 2.6 which is not officially launched is able to do so but apparently only by monthly subscription from designated data feeds, not sure whether able to import though. Not to mention portfolio and money management is out of the question. Seems like amibroker is the only one i know that fulfills my requirements, need advice on this. I may also consider throwing in the towel and settle for working with 1min data going with tradersstudio considering its edge for its portfolio and money management, able to factor in carry over swap rates and also its competitive pricing Lastly another newbie question, it seems like all platforms import data in the DATE, TIME, OHLC format. So for tick data does it mean that essentially OHLC has the same numerical element that is the current price as there is no OHLC with ticks.
