Any suggestions for a trading platform in the UK that will let me back test various trading strategies, ideally over 20-30 years covering commodities and equities, thanks
eSignal has these capabilities as do Interactive Brokers. The real problem is the expense of the data feed for these types of studies. If you already have a data provider you can use Meta Trader, Ninja Trader, etc., to do your studies and I think many of the services are free. That’s about it (to my knowledge) unless you’re ready to lease a Bloomberg or use a prime broker like RediPlus platform from GS.
NOTE I now post my TRADING ALERTS into my personal FACEBOOK ACCOUNT and TWITTER. Don't worry as I don't post stupid cat videos or what I eat!
