Incredibly slow file operations

First of all, thanks for this awesome tool and congratulations on the decision, to save the data in one single big file for each asset. This minimizes file system overhead and improves copy and backup operations. However, I don’t understand why you didn’t take the chance to improve the speed of file operations. Any mechanical hard drive is being killed by working on 28 Forex pairs simultaneously (single digit megabytes per second). I can’t even work on my computer in parallel, even when using a dedicated hard drive for this. Why not using a queue and let the program work on one asset at a time?

Hello, do you work with older TickDownload or the newer QuantDataManager?

I’m referring to the new QuantDataManager. Another disadvantage of paralyzing file operations are heavily fragmented files.

Risk Disclosure:
Futures and forex trading contains substantial risk and is not for every investor. An investor could potentially lose all or more than the initial investment. Risk capital is money that can be lost without jeopardizing ones’ financial security or life style. Only risk capital should be used for trading and only those with sufficient risk capital should consider trading. Past performance is not necessarily indicative of future results.

Hypothetical Performance Disclosure:
Hypothetical performance results have many inherent limitations, some of which are described below. no representation is being made that any account will or is likely to achieve profits or losses similar to those shown; in fact, there are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. One of the limitations of hypothetical performance results is that they are generally prepared with the benefit of hindsight. In addition, hypothetical trading does not involve financial risk, and no hypothetical trading record can completely account for the impact of financial risk of actual trading. for example, the ability to withstand losses or to adhere to a particular trading program in spite of trading losses are material points which can also adversely affect actual trading results. There are numerous other factors related to the markets in general or to the implementation of any specific trading program which cannot be fully accounted for in the preparation of hypothetical performance results and all which can adversely affect trading results.
