Best settings for genetic optimization?

Are there any help pages or descriptions of the various options that you can set when using genetic optimization (e.g. convergence type, max/min # of generations, replacement scheme, genetic algorithm subtype, etc)? And what settings have people found experimentally seem to work the best? Looking fo...

Need something like MaxIDDDrawDownPercent...

In assessing a strategy's performance, using MaxIDDrawDown is misleading for strategies which use compounding or pyramiding money management schemes. What seems needed is what is already provided in the Performance Summary when using the Portfolio Backtester - that is "Max Portfolio Drawdown (%)". A...

Cool, thanks. Now any idea why it's so painfully slow to pull the hour data from TS? I've got a modern 4-core desktop, fast internet access (~10 Mbps), etc so can't understand why pulling and graphing the hour data is so darn slow... What data service are you using? I wonder if it's a TS problem? Th...

For NVDA. Actually I found the hour data does seem to exist, although I'm not sure how far back it goes. In a chart window, I found if I format the Signal to be hour timescale and then to be 1000 bars from 2/27/2010 (today, for example) then only ~430 bars are pulled (roughly 3 months back). Increas...

Historical hour stock data?

I currently use TS for my data source, and it appears they only provide ~3 months of hour data (about 430 hour bars it seems). Does anyone know if this is just a TS policy that they don't have more historical hour data? Any recommendations on data providers which have substantially more (5-10 years)...

TS settings for ARCX?

ARCX doesn't seem to be included in the pre-configured exchanges with MultiCharts. Does anyone have the settings required for TS data to add as an exchange within QuoteManager (Price Scale, Daily Limit, Min Movement, Big Point Value, Time Zone)? And for future reference, is there a good resource ava...

How to queue up many Portfolio Backtester runs?

I have a trading system that I would like to test against ~100 different stocks. I'd like the Portfolio Backtester to test each stock one-by-one, using the same genetic testing optimization settings for each. Is there any way to set this up such that I don't have to manually start Backtester for eac...

Try to declare InitalCapital in your code. Input: InitialCapital (10,000); Value1= InitialCapital + I_ClosedEquity + I_OpenEquity; Yes, that's one way to do it. Seems the "right" (i.e. elegant) way would be to have some way to grab the value that's specified in the "init capital" field, either from...

Thanks all for your suggestions. The problem with using "PositionProfit" is that it only provides the profit (or loss) by position, but does not include into account he initial capital. Similarly, with I_ClosedEquity & I_OpenEquity, once the first trade is taken these will track the overall equity p...

How to plot a strategy equity line against a price chart?

In MultiCharts, how can I plot the equity line of a strategy I have developed against the price chart? And a related question, how do I get the current equity position in a strategy (GrossProfit and GrossLoss give me the gross profit and loss respectively, but how do I get my equity position)? Thanks.

Changing many symbol properties in the Scanner window

In the scanner window, there's an option to format a particular study for all the symbols, but there doesn't appear to be a similar option to change the symbol properties across all symbols. For example, I've got 100 symbols loaded in the scanner window and I want to change all of them to use 5000 b...

Thanks for the reply Fernando. Your cut-and-paste method allows for a nice easy way to add a bunch of symbols into the scanner window, but the data only gets loaded for those symbols if they already have been added via QuoteManager. You state that “All symbols will be created automatically in QuoteM...
