MT4 indicator function inputs.

I am currently writing tests for a C++ ATS as part of this I should like to write some unit tests for the various indicators to compare their results against some externally generated data. Is it possible to use MT4 scripts (or any other common platform) to feed some arbitrary bar data into a indicator and obtain the indicator result?

You can upload the OHLC data into the history of an exotic pair. Then open an offline chart for that pair, and run the indicators against that.

Thank you for your reply, would it be possible to point me in the direction of an example? I am familiar somewhat with MQL, but I am unsure of the specifics of 'uploading into an exotic'.

Tools => History Center => Import

When importing data, choose a currency pair which you will not trade with.

Once you're done importing that data, open the chart offline.

File -> Open Offline -> [Pick the currency pair and timeframe]

Attach the indicator to the chart.

Cheers.

Edit: All done now, I was able to simplify my ATR implementation greatly (which was based on the NinjaTrader indicator, but now based on the MT4 implementation).
