So it is intended that version A) test_bmps[num_bmaps] = bmap_create("test8MB.tga"); draw_quad(test_bmps[num_bmaps],...); uses twice the memory compared to version B) BMAP* source_bmp = "test8MB.tga"; // global bitmap ... test_

There can be many reasons, for instance that your graphics driver needs less memory for monochrome textures, using some compressed format. You could test this by comparing the memory consumption of different images, some monochrome, some with content

priceClose() is no feed from metatrader, but simply the close price of the recent bar. You won't enter trades in the middle of a bar unless you do that intentionally, for instance by using a TMF or entry limit.

Hi jcl, there is one more problem here. The problem is that in the second csv file I would expect that pd1 is the lagged value of pd0 and pd2 is the lagged valiue of pd1. But from data, this it is not true. Do you have any feedback from developers?

Yes, that's fine since bmap_createblack, as long as nothing else happens, just creates an empty bmap and has no impact on sys_memory or d3d_texbmaps.

I have a basic question about testing and life trading. I would like to trade only once per day, every day at 15:20-15:25, 5-10 minutes before market close. What is the right way to write a script in Zorro? I have daily historical data. If I use d

Sure, Bots and maybe Multiplayer. All playable elements should be done in the first 2 Levels.

I found a reference to Alice4b in another thread related to detrend I believe. This is the snippet I'm referring to: Code: function evaluate() { var TestProfit = 400; static int Count = 0; if(Balance > TestProfit) Count++; var Buck

Live volume was implemented some time ago, and historical volume theoretically also, but the latter does not work yet for all assets.

d3d_texfree only decreases with draw_quad, because video memory is only allocated when the bmap is rendered. From what I now learned, generating a texture fails not only when not enough video memory is available, but also when not enough normal memor

priceClose() used in a TMF returns the last tick, but my backtests are using 1-minute bar data, not tick data. This means when trading live, if I have a trading rule like if(crossUnder(Price,low)) ... where vars Price = series(priceClose()) and low

Ran the test, draw_quad makes the difference here - in your or my example code. With draw_quad, d3d_texbmaps increases and d3d_texfree gradually decreases! 1) Desktop (GTX 1080): E2005 appears after 201 bitmaps ~ d3d_texbmaps 1608MB, RAM usage of 165
