QQ: how come the LIVE trades on Okcoin.cn are totally different from bitcoinwisdom's?
I saw 2x9k orders that do not show up on okcoin?!
OKCOIN / Bitcoinwisdom
The trades is merged. eg: 14:17:50 is sum from 20:17:48 to 20:17:50. |

The charts uses the same function as test page uses, Still have no solution for the issue. I'm going to rewrite the charts to fix it, at least write a new mobile friendly version. When there is new update I will post it on the threads and it would be thankful if you could help me test the compatible.

Just write another test http://jsfiddle.net/gv7spbLc/The expected result is moving line without trailing. If the result is incorrect, change the flag closePath to 'always' or getContext2d to 'always' to see if the issue is solved or not. Thanks for looking into it. This test also works fine for me, but still no luck with the charts. Wish I could be more helpful than that! The test script also works fine for me - setting skip & once. Seems like the coordinates for clearing pattern are calculated wrong on some systems. Btw, I have two other PCs, also with win 8.1 and the current Chrome version and the charts work fine on them. Weird  The system use assign width to clear the whole canvas before and now it uses clearRect whole canvas, so it width and height should be correct. It shows correct when turn off the hardware accelerate for some users. so I think there is some thing conflict with hardware accelerate. |

No issues.
In the past testing, I met very similar issue which have trailing on a mobile device with hardware accelerate, but the trailing will be disappeared in seconds instead of always shows. And if the testing code works well, the site should be work well too. That's really weird, I have no idea how it happens, have to rewrite the code slowly and test often to find the cause. |

Looks like there is an area on the bottom left that is cleared instead of the main frame. This area is always black, except of the RSI graph that seems to be rendered afterwards.
Yep, the MACD lines are stable as well: Does it happen today or from hardware upgraded? And is there any error message in Chrome Console? Press 'Control-Shift-j' to open the console and then press F5 to refresh the page. |

Something funky going on here: Using the newest Chrome version https://bitcoinwisdom.com/markets/poloniex/drkbtcit seems to not refresh/clear the drawing surface as often as it should, because sometimes it gets re-drawn correct after a few seconds. Am I the only one that experiences rendering issues? chrome (38.0.2125.104 m) win8.1   This has been going on for a while now. It may have started after I installed win8.1, but I'm not sure... Doesn't happen in Firefox, but the chart is slow as hell there... I've created a small script to test the compatible. http://jsfiddle.net/x1ny28bh/1/Open the link and click 'ClearByAssign' or 'ClearByClearRect' in right-bottom, to check if the rectangle cleared or not. This works in chrome. I believe it may be a combo of chrome and win 8.1 as it is a mess for me on my 8.1 pc, but on my win 7 laptop and newest chrome, there is no issue. Also, it seems there is a trailing line of flat candles to the far right of the graph It looks like the canvas is not cleared. The cursor cross line uses same function, but according to screenshot, the cursor line is cleared correctly. If both function works in the test script above, it would be really weird, still have no solution to solve it. Have the exact same problem since updating Chrome a couple weeks ago. Updated it again today with no fix, currently running version 38.0.2125.111 m, on win7 64bit. For the first time in about forever I actually have IE open on my computer because of this, sad day  . fwiw that test script works fine for me. Now I've changed the clear canvas function. Hope it could work. |

One question/feedback about Volume indicator:As far as I know, Volume indicator print in bars the sum of buy orders and sell orders if there are more buying orders, the bar is printed in green color, if there are more sell orders than buy orders is printed in red. If we take a look to this volume indicator in bitcoinwisdom we can see that the color bars of the indicator are printed depending on the price, independently of the number of buy orders or sell orders that occurs in that period of time. IMO, I think this is wrong. Why? i.e: -Chart time-frame of 1H (or another one). Current price is at 299.9 (candle open at this price). Below 299.9 is almost clean of bitcoins in the OB (it takes a little amount of bitcoins to take the price down). If I put a limited sell order at $300 of 28.000BTC(i.e), I am creating a "wall" over the current price. If the people buys 27.999BTC (1 BTC left on the wall) and after this one person sell just 10BTC, the result is: - The number of buying orders executed >>>>> than selling orders executed - Candle opened at $299.9, - Candle closed at $390 (or any other price under the current price) - The price candle have to be red because it closes at a lower price than it opens An here is the good one: - The volume bar have to be green, no matter the price that the candle close, lots of more buying orders were executed than selling orders. Now, the fact is taht the volume bars ar of one color or another just depending on the price that the candle open and close. The volume indicator actually is not indicating if the volume of this bar at a certain timeframe was powerfull at the buyer side or at the seller side, they jus t print if the candle close lower or higher the open and in my opinion this is wrong and can confuse us. Anyway, your site looks gorgeous, love it and I'd been watching it since your beginnings. Goog job  screenshot of what I'm saying: It was implemented long time ago, but it won't applied currently for no suitable colorscheme. Maybe it will be an option in future. You could use 'Bid Ratio' indicator to check the bid ratio, but not all market support that indicator. |

Some weeks ago something is bad in 1m, 3m and 5m, the candle open value is stuck.
replicating the bug:
Open some market in 15m.
Change it to 1m.
Change to 15m.
Wait some minutes.
Back to 1m: every candle start at the same value.
What's the market? I cannot reproduce the issue. Is the time correct? |

Difficulty chart has not updated in almost 3 hours.
Thanks for reporting the issue. It is fixed now. |

not sure if this has already been addressed (apologies if it has)
On the MACD indicator, there are volume bars in the background. Sometimes they are filled, sometimes they are not. Could you explain the logic behind a filled vs unfilled bar?
It would be nice if it was included in the "help" section of the site, but at the very least I'd like to understand this for myself.
bump  Unfilled bar: The value is greater than previous value. Filled bar: The value is less than previous value. |

Hey, Bitcoinwisdom A quick question: How do you calculate the aggregate (or average?) price of a currency on the frontpage, https://bitcoinwisdom.com/Is it weighted by volume on each exchange? If so, volume of a period, or by trade? Or is it simply a non-weighted average of the last price on all exchanges? Hey, any chance you could take a quick look at my question from a few pages ago? It is weighted. The weight is volume*volume. (Price*Volume*Volume+...) / (Volume*Volume+...) Cool, thanks. Also, congrats on 'hero'  Thanks. Just notice it. |

Minpal seems to have broken BItcoinwisdom -.- Undefined index: mintpalcaibtc /var/www/bitcoinwisdom/tmp/app/cono/initialize.php : 186
The bug is fixed. We apologize for any inconvenience. Because MintPal has been offline for 24 hours, all volume is 0 in 24 hours. and MintPal in 'Markets' menu is ordered by the volume in 24 hours, then it returns mintpalcaibtc which has been removed. it cause the site broken. |
