[amibroker] Re: limited RAM usage

The current versions of AmiBroker do not fully utilize multiple CPU cores. If you are running optimizations, you can experiment with MCO in the files section of this group to see whether multi cores will help in your situation. Mike --- In amibroker@yahoogroups.com, zozuzoza zoz...@... wrote:

Re: [amibroker] Re: Data And PlugIn Speed

Hello, Chart refresh is independent from data collection. It means that plugin can collect even 1000 updates (ticks) per second per symbol, while chart will refresh 10 times per second. If that happens, during 0.1 sec you will see 100 new ticks arrived and displayed on chart. It does not make

Re: [amibroker] Re: limited RAM usage

Hello, It was explained in the past. My test have shown that single core using array arithmetic fully saturates RAM bandwidth and single core already waits for RAM, thus adding more cores makes AFL running slower, not faster if data do not fit into CPU on-chip cache. Using more than 1 core makes

[amibroker] Wierd trailing stop problem in backtest. Please help????

Hi. Can anyone help? I am backtesting a system which uses Buy,Sell,Short,Cover variables,(TradeDelays,0,0,0,0) on close, and also stopTypeProfit(8.25%) and stopTypeTrailing(5.25%). The problem that I am having is in backtesting. One of the trades is a long position on the close, at $45.00, the

Re: [amibroker] Timing test example between Arrays and Loops

Tomasz, I had a typo in the previous results. The 1,000 and 10,000 cases were swapped. I still can not explain the differences I am seeing. I have tried rearranging my code in many ways and the differences remain about the same, 2x more time for 10x shorter loop. There might be some

[amibroker] Re: Data And PlugIn Speed

Tomasz, Thanks. I am starting to understand now because I have read a few of the posts on refresh etc (thanks to Herman/Dennis .. who seem to be the leaders on this, and others plus, of course, your good replies, here and there). I seem to have moved on to AFL 201, without even noticing. I
