The process of importing data from MetaTrader is very simple and straightforward.
1. You download the script provided in the BO Tester -> Tools -> Data Import page
2. Run this script on a MetaTrader chart. The script exports the available data for that symbol in files.
3. Drag and drop these files in BO Tester
4. Change the Data Source, Symbol and Period in the Editor.

Please sea a more detailed instruction here:  Data Import

If you have problems on a particular step of the process, please post data file, screenshots or log files. We will examine and fix the problem or will find a workaround. (We created that application from scratch without an analogue and probably we can fix any issue with it or to make it working smoother and better.)

..

N.B.
Please post the separate questions in separate topics. It will make it easier for the other users to find and use the information later.

Binary Option Tester doesn't include an Optimizer yet. Can you post more detail, strategies and screenshots? We cannot comment and analyse general statements.

I have followed this process and uploaded the json extensions files.

The issue is that the data range of the historical data I uploaded was far larger than what the BOT made available for me. The starting day is 01/01/14, where BOT reads bars, and they are far less than the starting date I have data for (01/01/2014). The maximum bar count for all timeframes on the MT4 when running the BO Tester Data Export script is limited to 2048.

How can I increase this? I tried the home button but there is no change. Is this data my Dukascopy data or the data downloaded from the history centre? And if the latter is true then how can I import the Dukascopy data to BOT? Which MT4 folder does the script get the data from? Does the fact that I have made the .HST and .FXT data "READ ONLY" BEFORE using the BO tester Data Export script play a role?

This is true but when there is 0 spread used any data really would do the job, is that correct? All I want is to use MT4 as a second testing mechanism an for ease purposes.

I have no doubt about that. Although on a different matter I would prefer to have a nice graph showing the equity curve, information about %itm, drawdown and all the rest, and have that in a document that I can download evey time I perform a test. MT4 allosw that. BOT allows to download only the trades results. Wouldn't it be nice I if this document included a balance chart, the backtest output under Report, and simulation results?

Saying this reminds me that all the EAs, when tested on MT4 and output the backtest results onto the journal, the results DO NOT include the closing price of the trades. I find this really important, especially for BO. How can this be changed?

There is no spread in the Binary Options trading. The broker provides a Payout value in per cents, which determines the profit at a successful trade.

Example.
Lets trade with $10 (called stake) and the Payout level to be 80%.
When you open the deal, you lose the stake.
If the deal ends on profit, the broker returns you the initial stake and gives you also profit = stake * payout. In our case the profit will be $10 * 80% = $8.

MetaTrader doesn't have a concept for payout. Also the profit and loss in forex depends on the difference between the position's close price and the position's open price. This is completely different than the way the BO trading works. It is useless to try backtest BO strategies in MT with the MT tester and the provided from MT stats info and tools. There is no way to see balance and positions in the MT tester, because it cannot close positions in the way BO trading works.

I see you want to confirm the BO Tester results with MT, but this is not possible so far.

BO Tester is the world's first tool for backtesting BO strategies and "unfortunately" a second opinion is not possible. This doesn't mean that BO Tester shows random results . You can review the complete trading stats and position chart in the Report page.

Monte Carlo is not an optimizer. It is a toll for testing the robustness and the reliability of the strategy.

The BO Tester's Monte Carlo documentation is under construction yet, but you can take a look at the FSB Pro documentation at the topic: Monte Carlo

Not exactly confirm the results, I am sure that what you've build here works, hence I am here   I would say that I want to find discrepancies, if any, in data and test EAs in various of brokers and with various data, rather just rely on one broker's data, for obvious reasons.

Can you make this report page downloadable? i.e the stats info, balance chart (not too important) and the transactions log into one document (any format)? At this point I can only download the transactions log.

Yes I am aware. The EAs however do not display the closing price when run on MT4. See picture of the log file on MT4, it only displays the opening price, not the closing price. Is there a quick fix via coding for this so the closing price can be displayed as well?

This is a log of the Alerts. When there is a signal, the EA rises an alert, so we can execute a deal manually. The deal expires alone and we don't have control on the position. Therefore, we don't need an alert for closing it.

Is execution manual in Signals EA and automated on Trading EA? Are there anyway any possible ways of knowing the close price, that is on MT4 journal?

Yes. Exactly.
