Hello. This is an update to a problem I have been experiencing since 12 Sept. First of all thanks guys for your patience in trying to resolve this, however it does not appear to be your problem. I have been trading with no problem for 18 months using a USB Modem stick from Vodafone (in Spain) I could download 120 days of historical data from zenfire and it would literally take no more than a minute or 2. Since the 12 september it takes ages to open a chart with even just 5 days backdata this is in 6.5.18. In NT7 it´s impossible. The problem lies with Vodafone, recently Vodafone and other mobile service providers upgraded their networks to implement the 7.2 mps - 14.4mps connection speeds the upgrade identifies itself in the connection software as an HSDPA connection. Great!!! My internet browsing experience has improved dramatically, I can now partake in webinars watch streaming video with no interruptions download NT updates of 54 Megabytes in 4 minutes, its fanatastic, but, but, but Vodafone have been co operative and have tried to tweak the connection in my area, thank you Vodafone, but the problem remains the same. So my advice to any one who uses a mobile connection, reduce the lookback period to the absolute minimum that you need for your indicators and reduce the number of charts that you have open, this will reduce the download time and make it possible to trade.
My question is. What is the difference between the data used to transmit historical data and that used in internet browsing, I have used TCP connection software to monitor what is happening and for general browsing megabytes of data is coming down the line in minutes, but connect to NT and only bytes of data comes down the line, as far as I can make out we are not even talking about large files just Kilobytes. If someone could educate me as to what the difference is I might be able to point Vodafone in the right direction because from their point of view the connection is doing exactly what it says on the box.
As an aside. Fascinating. For you non american based traders. I used a trace programme and found that the connection from my home to Ninjatrader takes between 17 and 22 hops generally going from madrid to london to frankfurt to madrid to london, sometimes to italy, then the rest of the hops are stateside, my point is, that despite this my slippage is minimal to none existent so zenfire (Rythmic) must be doing something right. So if you are experiencing slippage try checking your route the delay is probably occuring enroute.
