JForexUtils: A useful library for Dukascopy's JForex

Hi JForex developers,

I've created a useful java library which eases the day-to-day programming in JForex.
It is for free and you can even use the source code for your own ideas and extensions.
I've written the first part of the documentation at the article contest section of Dukascopy -> click; you will find detailed information there.
I will update this thread as soon as there are new articles.

All the best and happy trading,
Juergen

Part 3 is online.

great work...

I'm a big fan of builders..

could you explain what is going on here?

return ConcurrentUtil.isStrategyThread()
? execute(() -> orderSupplierCall.get())
: execute(strategyThreadCall(() -> orderSupplierCall.get()));

I'm trying to understand how the callback functionality was implemented, it is very interesting to me.

I have following question.
In MT4 there is following function:
double iMACD(
string symbol, // symbol
int timeframe, // timeframe
int fast_ema_period, // Fast EMA period
int slow_ema_period, // Slow EMA period
int signal_period, // Signal line period
int applied_price, // applied price
int mode, // line index
int shift // shift
);
so, in my code, if I need to get macd value from current timeframe I can use following code:
double val = iMACD(NULL, 0 ,12,26,9,PRICE_CLOSE,MODE_MAIN,0);
If indicator or strategy work at 1 minute time frame, but I want to see macd at 5 minute time frame I can use the following comand:
double val = iMACD(NULL, PERIOD_M5 ,12,26,9,PRICE_CLOSE,MODE_MAIN,0);
If I want to get value of previous 5 minutes time frame, I can use following code:
double val = iMACD(NULL, PERIOD_M5,12,26,9,PRICE_CLOSE,MODE_MAIN, 1 );
If I want to get value of 10 minutes before, I can use this line:
double val = iMACD(NULL, PERIOD_M5,12,26,9,PRICE_CLOSE,MODE_MAIN, 2 );
Regarding to this I have two questions:
1. How to get value of macd from time-frame different from which custom indicator is executed?
2. How to get value of macd from time-frame different from which custom indicator is executed and if time frame is not standard ( for example timeframe of 28 minutes )

Is it possible to use your utils in order to implement such functionality in indicator or in strategy?
