I know that there are some chart types out there that do take a long time to load.
I have been using RenkoHybrid and ChannelTrend chart types for 2 years and have not noticed this issue.
Is this occuring with indicators already added to the chart? If you add a new chart or update a chart without indicators are the cpu usage values similar? How much historical data do you normally load.
Also, if you use even number tick bar size settings, it will reduce the cpu time needed by reducing the number of fractional calculations needed to calculate bar construction on the chart. I have updated the web site to reflect these preferred settings.

Can you help answer these questions from other members on NexusFi?
Yes, I had the same issues. Until I removed indicators that were added to the chart type.
It would lock up my PC/NT (which isn't a slow one) for at least 20 seconds. Loads quickly by itself, but probably something with the way the indicators are analyzing the chart bars drawn?
@monpere, how goes your testing? I am finding the bars move so quickly that trying to get an order in manually or automated any where near the second bar after a reversal is near impossible. Are you finding this? And what have you found to filter the the chop successfully? Please share what you feel you can. Thanks.
I tested with market orders, and generally there is a couple of ticks slippage. They seem to perfrom pretty well outside of chop, but chop areas become huge killers, they can take the profits away very quickly. The testing I did was just applying my current strategy to these new bars without any alteration. I have not thought around the chop issue yet. I would have to do some more testing and analyzing for that. Given that these are manufactured bars that do not show real price action, I cannot backtest them without changing code to account for that, so my tests have just been in live market sim. Obviously, that way it takes way more time to play with these new bars.
I only used them during the trial period. They seemed to work ok, but not significantly better then the regular range bars I use. I personally found them to be a bit visually deceiving as they smooth out the price action by artificially repainting the bars. This effect makes your indicators look totally wild. I use RSI and stochastic, and the indicator patterns using the trend bars were totally different then with any other types of bars I've used, so not sure the traditional indicator usage would work all that well with them. Overall, using the trend bars with my particular automated strategy did not significantly increase the strategy's profitability. Gabryele seems to do very well with them in the Blueline Delight strategy thread, so you may want to check out that thread.
Sorry about the nomenclature, by repainting, I meant that the bars on the screen are not showing real price action, maybe a better term would be artificial bars, visually altered, or OHLC altered bars.
