Definitely the product the data is just the feed. When I watch videos of Pros I rarely see other than the TT occasionally Sierra and Jigsaw so thought I’d open this for discussion and see what everyone thinks.
Jigsaw, Sierra, Bookmap, TT, all apps/software, all prone to glitches. Never ever trust an app. If you're trading with real money, have at least 2 apps connected to your trading account. If one breaks you have the other one to manage the position. Also, have 2 computers, one app in each PC, just in case one PC crashes. Also, have a 4G connection ON in your phone, so you can quickly switch in case your line go down, and lastly have your PC's and router connected to an UPS in case power go down. Talked to a trader that has his trading accounts connected to 3 different apps, all running the same trading system. This is my life he says, my money, I don't play with my money. If one of the apps crash, I'm relaxed because the other 2 apps are running. TT is the most used by professionals because they were the pioneers in terms of DOM trading. Back in the day, traders would pay $600 a month to use XTrader. TT has time in their favor, they had all these years to build a robust infrastructure. All the others are recent companies, building now their infrastructure. Clearly targeting the retail traders a market that TT has very little interest since it's not there where the big money resides.
TT has lost it's edge. HFT has eaten their lunch. It used to be possible to make markets with TT but try doing that now and you will lose your pants.
You really need to take with a grain of salt any video you can possibly watch like this. Anyone who makes this kind of video and is not selling something has some deep insecurity they are addressing with the video. The last thing a real trader is going to do is show you their strategy.
what do you mean lost it's edge ? Many HF traders are using TT. Do explain please. I think you have a different definition for MM'ing
HFT firms are fully automated. MM is quoting at the bids and asks and getting filled but without price moving 1 tick straight away against you. Now it's almost impossible to accomplish that anymore.
