    There comes a point when zooming out where my chart goes from looking like a chart that’s easy to read and understand to looking like crap. When you reach this point it’s a huge jump and it’s probably the thing I dislike most about this software. See screenshot, this is the same chart simply zoomed out 0.01% more on the bottom one.

    Other apps manage to handle zooming out much much better(ie trading view, ninjatrader), I wonder why PRT cannot figure it out.

    I think all platforms have their pro&cons… You have to evaluate and choose.
    PRT is continuously working hard. There is a saying in Spain “nunca llueve a gusto de todos” that could be translated as “it never rains to everyone’s liking”

    2 or so months ago I worked out this issue with zooming (on this forum somewhere) and this is a V12 bug, not present in V11. “Of course” nobody takes action upon this, and No, I did not file a ticket for it either.

    That is very interesting, because it would be the sole reason for me not using NT. Unless you want to spend 99% of your time on zooming of course – then NT works too. Maybe they have a zoom course ? 🙂

    #Peter St, I think I can recall the post you mention, but can’t find it either.

    Here’s a few thoughts about zooming and candles I found on my travels.

    When zooming out, there’s a  change from the smallest possible size a candle that can be drawn, body/wick, to a line representing the range of the candles.

    I’m using a 24″ 4k monitor which allows about 1200 candles to be display before this change, at full width of  screen.

    Changing to 1920 x 1080, this drops to about 550.

    1366 x768 drops to about 400.

    Multiple monitors can increase the number that can be displayed.

    So depending on what device is being used, you can have  different results.

    Additional , the physical size of the display, is going to affect  what visually your seeing.

    Also the more bars you display, the range of max high/low value can, adjust the Y value scale.

    Resulting in squashing the candle/lines.

    So,  if large number of candle are being displayed, its best to use full width of screen.

    And the height, on the range of max high and low to offer a clear view.

    At this moment I see no difference any more between V12 and V11, so no (extra) issue there.

    Hi several, what you see happening is the necessity to make the candles smaller because else they would run into each other. And Yes, this happens from the one scroll position to the next (one scroll tick difference). This just can’t be avoided. Btw, I forgot whether the bar distance can be set; that would help.

    But what I also see is that your background color does not like the color of the wicks. See below 1st pic for an example where it does work (that too was scrolled one tick too far, like in your case). This can be solved by (obviously) changing the background color, or else by changing the candle color.
    However …
    Also see the 2nd pic. There my wicks have disappeared too. But hey, there the candles are 1 pixel wide now, so what to do eh ?
    Resolution of that monitor is 3440×1440 at 92cm wide (this is more rare). The forms you see in the pics are 9,5cm wide.

    Personally I think PRT has the best zoom facilities out there. Of course I don’t know all of the platforms, but NT really bears the worst (possibly because of the lack on that course 😉 ). And just saying : without a “best” zoom facility it would be impossible to build decent AutoTrading systems. This also requires to be faaaast with it.

    Hi,

    I’ve been trying Trading View for a few weeks (Premium Plan EUR 59.95/month):

    Max. 20k historical data (it stopped already here for me)

    Very limited back testing

    No optimization

    Not a “built-in” broker (here you must work yourself with a third party that sends the data to the broker, very cumbersome and according to the comments unreliable)

    Much more difficult language than PRT

    Very quickly back to PRT… 🙂

    @PeterSt

    I’m sorry but it totally can be avoided. The zoom on TradingView is perfected completely linear with no jumps. NinjaTrader also is far superior when dealing with the same issues and the jumps are less noticeable.

    It’s simply poor design. I understand the problem but PRT solution is lazy and bad where you go from a easy to see chart to one where you cannot even see where the wicks and bodies start and end. The white color scheme is essentially unusable because of it.

    I prefer to use white because it’s easier on my eyes than light candles on dark background.

    And the subject of zooming, the zoom shortcuts don’t work on Mac. Still waiting for a fix from support. You cannot zoom in on a specific candle also. Zooming is without doubt one of the weakest areas of the app IMO.

    I’m still using tradingView for general charting. I use PRT for trading and scalping. PRT is far superior in that regard but for quickly moving around charts TradingView is much better IMO. I love being able to lock a chart to a specific ratio and use the zoom wheel to zoom in and out accurately to any point and retain the same ratio.

    I cannot get past these ugly zoomed out charts with PRT. With ES Futures it only takes a day’s worth of candles or so before the chart with 2000 ticks turns into this ugly version of the candlesticks that completely renders the candlesticks useless as they were intended.

    See screenshot, TradingView vs PRT. Same 2 minute chart with same zoom level. It’s not even close in terms of quality. The PRT chart looks like some inferior mobile phone version on a smaller screen. At this level Trading View has a 6px wide candle body and 2px wide wicks. In comparison PRT simply shows a 2px line with 4px empty space in between each candle. On the tradvingView chart you can clearly see the large wick on the low, not possible with the PRT implementation.

    This is not a technical limitation they are bound to. I think the fact they leave some much white space between the candles is the reason why they becomes so hard to see and they have no room to differentiate the wick from the body. Also, once you get to this style of chart in PRT the ‘width’ setting of the candle stick does absolutely nothing.

    When I zoom out, I am looking at the overall view of ups and downs, not where wicks and bodies start and end on a candle which formed 100k bars ago.

    If / when I do want to focus on several historical bars I use the ‘Zoon Zone Mode’  (takes 2 seconds) which makes it very easy to see wicks and bodies 100k or 500K bars ago.

    See attached for the Zoom Zone Mode button looking at wicks and bodies and trade exits in Jul 2023 on 100k bars on 5 min TF.

    Everyone is using their apps differently I guess. I’m switching between a scalping zoom level and 1-3 days zoom and I like to move my charts around. I’m drawing my trend/resistance lines on 1-3 day level zoom where bodies open and close, not at the ends of wicks. This is why it’s important for me to see the wicks. I’m not zooming out to 3 months and expecting to see clearly defined bodies and wicks with 1 minute candles. But I think even the biggest PRT supporter can objectively look at the screenshot I posted above and see TradingView is showing far superior information at the same zoom level on the same screen.

    I know you can set up ‘unit’ buttons to switch between say, 200 units and 500 units but the interface buttons are not entirely responsive and don’t always register clicks. I asked support if they can add shortcuts assignable to these buttons to get around this bug.

    I have favourite buttons for TF as you can see on my screenshot I posted above …  5 seconds, 1min, 5 min and 1 hour … takes a second to switch between each view to get a big picture view of price.

    I manual trade using 100 bars on 5 second trading Timeframe … so probably very similar to you?

    These buttons are buggy for me so can’t use them, clicks don’t register 40% of the time and the buttons just flicker.

    Are you on a MAC or PC or what?

    Maybe you have too many Charts and Lists and such like open at once?

    Maybe you have far too many Algos listed in the Code Editor  section?

    The last 2 above, I have found, result in ‘weird stuff’ like you are experiencing.

    I don’t get any flickering and non-registering of buttons etc.

    You sure we are talking about the same buttons … a ‘Favourite Timeframe’ button??

    Mac, M1 Max 32GB of ram. PRT is running very stable and fast. I only have 2 chart windows open. Both ES Futures 2000 tick. One is 200 units, the other is 400 units or so and I size them so they overlap on the edges of the screen so this way I can switch between them with one click. This is the workaround I’m using for the bugs I face with the app.

    You can see the problem here with the buttons not always registering clicks; https://youtu.be/Gx997aFT6tM it’s completely random.

    I don’t use algo’s either FYI. Only an indicator is 21 EMA.
