If it could help

they are more information in TS help than in MC help

HighD is documented in TS 8.4 Easylanguage help.chm ( 3.5 Mo )

not in MC 5.0 Powerlanguage Help.chm ( only 0.2 Mo)

I've thought interesting to post here some info (autotranslated in English) founded on the net about

-Easy Langage (tradestation '91)
versus
-PowerLangage (Multicharts '99)

------------------------------------------------------------------------

Multicharts is on this day the most serious alternative in tradestation.

It is indeed about a mini tradestation, a real clone of this last but whose developments advance more quickly and that considers to really push the things more loins than its eldest especially.

Multicharts presents many assets. it offers a total connectivity in the first place to all fluxes of the market, including those of tradestation Securities. But what makes its biggest strength that is the Power Language, a clone of the Easy Language permitting to import all your tradestation scripts. Compatibility not being assured to 100% again, it subsists some instructions at the present time EL non holds in charge but nothing of blocking. Until now what I could not compile could be comfortably shaped.

Of the comparative tests between TS and Multicharts done on several Backtests, all based on the same data of TS Securities, showed some results 100% identical to the pips near. That it was about the trades, the prices, statistics presented in the reports or the Equity Curve, all is completely identical. To note that the shape of the reports is however different since Multicharts adopts a presentation inspired of the reports eSignal. There is not therefore to expect bad surprise when to the motor of backtesting.

That remains the "tradestation Like" however therefore subject to the same limitations that this last. Out of the question for example to bring up systems of scalping since it is impossible to have knowledge of the book and to manage the investments of orders (Buy the Bid / Sell the offer), Multichart as TS emulates the executions merely and transmits them in Market Order to the next tick, that remained perfectly maladjusted to the trading high frequency and even less to the scalping on the future of indications or rates (for that a tool as SmartQuant permitting to place the orders really and to modify them to work the order book is adapted very more). Now for the intraday in 15 minutes or in Hourly that remained of very far the simplest of the solutions to put in work. To note however that a next version of Multicharts foresees to be able to place and to manage some orders already in place at the broker, what opens the way to a more sophisticated automation.

Multicharts especially puts the accent on the performances of calculations. From that point of view it surpasses tradestation very extensively.

First of all the very architecture of the software is completely Multithreaded what permits to continue to work during an optimization or the calculation of a complex indicator. When you throw an optimization on tradestation, you are blocked, useless to tempt to open another chart or to throw another calculation, its old and monolithic architecture blocks you completely. On Multicharts you can continue to browse your workspaces, to open new charts, to do other backtests, brief you continues to work as if of nothing was.

Then the use of the Multicore permits a gain of performances meaningful compared in tradestation. I compared TS 8.2 and Multicharts 3.1 on the calculation of one of my personal indicators. I chose the most complex in term of time of calculations.

The Calculation is done on a portable Sony Vaio Core2Duo from a historic GBPUSD in bar 15 active min of 10/2002 at 31/05/2007. The historic descended TS has been imported on Multicharts:

Time of calculation
tradestation 8.2 16:24 min
Multicharts 3.1 10:00 min

One notes that one passes of one time of calculation of 16 minutes and 24 seconds on TS to 10 minutes on Multicharts. The indicator's results are completely identical between the two softs, there is not artifice of calculation or mistake. Multicharts is therefore practically 40% faster than tradestation on this simple test.

Those that wondered what interest it could have there to use Multicharts on a TS flux since in this case one has tradestation as necessarily have just found here the answer.

Numerous improvements are to the program with in the first place a Speed increased from the Backfill of the local data (the big weak point of Multicharts). After some tests one notes a clean improvement effectively since henceforth the most recent data are displayed while the rest continues to be in charge (before it was necessary to be patient until the complete loading to have the last bars). The system seems to function by groups of 100 000 bars, it charges by pieces in some sorts. The remains together however again in values a little too elevated since it is necessary one minute before having a complete chart in 5 min on 5 years and half, either 324 000 bars (for the same period in 1h the time is the same). Optimizations can be brought again to this level.
