Hi, I love the Color Bar based on alert condition however when I add a few of them I notice CPU usage goes up considerably. Does "Evaluate on Bar Close" only get run at end of bar thus use a lot less CPU? If for example I am running this on a 1 min chart and notice CPU is a lot do I have the option of creating a new 1 min chart and setting Chart Update Interval in Milliseconds to like 10000 which would run it only ONCE every 10 seconds correct? Then if that's the case use Study/Price Overlay to plot it on fast updating 1 min chart giving me best of both worlds fast ticking chart to see quick price movements and my advanced studies that I don't need run every update or even second and want CPU usage to be lowest. Am I correct in assuming this is a good course of action? |

This is a super efficient study. So we do not know why you have a problem to begin with. Doing calculations only on a bar close will make next to no difference. We have no idea why there is a problem in your case. Makes no sense to us. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

I'm using 3rd party studies such as TWFX Ask Volume at Price for Bars (High to Low), Bid Volume and also both for Low to High to sum up amount of buying/selling at top 3 points and bottom 3 points each bar and doing statistics on that data to see for instance when there's lowest selling in last 10 mins at bottom of bar, highest and same for top. I have many Color Bar Studies based on various order flow events etc. So there could be 20-30 color bar on alert and checking so much. So having it at close doesn't do fewer calcs? Putting it on another 1min chart with a 10 second update frequency wouldn't run cals far fewer times? |

You really have to do your own analysis and you use your own judgment on what is best. It is really impossible for us to know. The Color Bar Based on Alert Condition study by itself is very efficient. Using a separate chart in your case seems to make sense. It should be fine on this other chart to use an update interval of 2000 ms. But once again you have to make your own determinations. We do not know.

Ok one last question does it look at the rules like C+ does in other words if FIRST rule is false it quits or does it go through all the rest? That way I can make first rule the most restrictive etc and will be far faster. |

I'm buying a new PC for trading curious how much of a difference in speed and CPU % a more expensive graphics card impacts? I really enjoy seeing the price move FAST as the markets do but often have to tone down speed so PC is responsive. Would the top of the line NVIDIA card make a huge difference or minimal? |

The Alerts do use this mechanic, so you would be best served to have the most restrictive test up front. But we would be surprised if this is really going to make much difference. But as noted with the other items, you would have to try and see how it affects your particular setup. Would the top of the line NVIDIA card make a huge difference or minimal?
We have set this as a User Discussion for others to give their thoughts on how Nvidia cards have worked for them. For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

Thank you so much! Some of my alerts have 20 or so rules so this will definitely help. Twenty or thirty color bar studies with a few dozen rules in each on a chart with fast response time to see micro up down moves does use up CPU on my 8 year old machine which was awesome over $4k but now need new one but I'm sure recoding alerts will save 0.5 to 1.5% which will make charts more responsive dragging stops etc.
