Personally I use CQG which is the best charting I have ever used. eSignal is good as is Genesis, but having used all three I much prefer CQG. A little above average in price, I think the basic package is £360 - but you get what you pay for...
I'm trying Optimal Trader, which is reasonable priced ($99) and a bit technical (if you want to)
Anyone else here who has tried it? It's quite new and a bit different than the others...
Until now I have mostly used technical analysis for stocks and mutual funds, but I'm currently investigating the possibilities in the Forex market with Optimal Trader
