How reliable are free sources for historical data?

Has anyone used free sources like histdata.com, dukascopy, forexsb to train models or backtest their algos?
I am working on training a model to trade forex pairs. Still experimenting with the idea and don’t want to invest in an data api before I have a solid strategy.
Wondering if I can make use of this data to test the model with this data and move on to test the model with something paid afterwards OR just go with a single data source as best practices would say.
Thanks in advance!

Where to find quality Forex tick data?

I downloaded EURUSD tick datasets for several years back from Dukascopy and found out that the data is trash. Many missing periods, sudden inexplicable jumps from one hour to 2 hours in the future etc. There's no way for me to fix this, the quality is simply trash.
Where can I find quality Forex tick historical datasets? I found a few sources googling around, but it takes a fuck ton of time to download it and check, it's even riskier if I have to buy it. Does anyone have any proved sources?

Dukascopy/Tickstory forex volume data is not trading volume

Getting Dukascopy / Tickstory forex data (I think the most famous free source of forex tick data), I noticed that the tick data csv has "bid volume" and "ask volume" columns.
Getting bar data for them, the "volume" column is just the sum of the "bid volume" of all ticks in the bar.

The way I understand the tick data, "bid volume" and "ask volume" are not real trading volumes, but rather the quantities in the top level of the order book (highest bid and lowest ask). If this is true, the "volume" data column in the bar data is very misleading, and this very famous and widely used data source does not contain 1) actual trading prices 2) trading volume.
Am I missing something? Dukascopy data can be obtained here: https://www.dukascopy.com/plugins/fxMarketWatch/?historical_data

Best bid & ask size data for forex available?

Hi,
Currently, I use Dukascopy free forex data to train an algorithm. The data contains bid & ask price and bid & ask volume for all ticks. As far as I understand, bid & ask volume is the trading volume and not the best bid & ask size (the amount which is offered for the best price).
Does anyone know of a data source which contains the bid & ask size as well? Generally, I am willing to pay something for it provided I get a half a year of historical data first for free (or for a reasonable fixed price) to test if it is useful at all.
So, I need the following:
- Historical forex data (tick or 1s-15s bars)- Live forex data (tick or at 1s-15s bars)- Columns: time, bid & ask price, bid & ask size, bid & ask trading volume

Any suggestions?

Edit: I am a student. Maybe that helps to get free data from a expensive provider? :-)

My 2016 Study of 10 Forex Calendars

I have finally updated my 3 years old post about economic calendars according to the changes in these tools. This time, I've removed Yahoo, ForexSpace, InstaForex, and FXOpen from the list due to lack of any interesting features. Replaced them with: Dukascopy, Econoday, Trading Economics, and WBPonline.com. The most interesting findings are:

Do you think someone will buy my C++ source code of a backtest/trade system?

Hi all,
This is not an AD, but I'm asking your opinion whether someone may be interested in my system, or whehter it's worth that I do some work to find a buyer. This is a backtesting and trade system, not strategy.
Main functions and features: * Written in C++, using Qt framework. Can run on Windows, Linux, and Mac. * Console program, very fast. * Currently only support Forex, but it's easy to extend to support other markets, such as Stock. * Backtesting. Candle bar based backtesting. It's not difficult to support tick based backtesting. * Optimization. Currently only brute force is supported, but it's quite easy to plug in other methods. * Walkforward testing. * Multiple threading. OpenMp is used for multithreading, each backtesting task is allocated on a CPU core. * One robot can use multiple instruments and multiple time frames. * Live trading system. Currently Oanda REST API is implemented. One robot can place buy/sell order on different account, to avoid no-hedging limitation. I have used it on my live account, and it works well. * Any more trade platforms should be able to be integrated to the system, such as FIX, but I didnt do any investigation yet. * Some indicators are included. MA, RSI, MACD, PSAR, etc, using ta_lib. New indicators can be developed easily. * Dukascopy data download. Incremental download tick data from Dukascopy, very fast. * Oanda data download. Using Oanda REST API, incremental, very fast. * Simple charting. So the report contains a balance chart, very intuitive. * Some other features, such as convert Dukascopy tick data to internal candle binary data, convert candle data to MT4 CSV, etc. * Unit testing. Some key components are unit tested. * High quality code. I'm an experienced developer. You can check my code quality and style from my open source C++ library, cpgf, on github, though it's not finance related. * Very good performance. The bar based backtesting system is highly optimized. * Since the architecture is good, the system can be used as either a program or a library. * About 50K lines of C++ code. * I spent about one year partial time on it.
My question is, do you think anyone will be interested to buy my source code? And how much do you think I should charge for? Or beside selling the source code, what do you think I can do to earn some money via the system? My original purpose developing such a system is to use by myself, but I'm not sure when I can find a good strategy to earn some money for me.
Thanks
