Not sure what you mean by "cleaner". That is why traders use Lightspeed Traders, which is built for speed and has many of the items that other retail and professional platforms have including: https://www.lightspeed.com/trading-platforms/lightspeed-trader/platform-features/. I use TOS for my small IRA. When I bring up a chart it often lags for 10 to 30 seconds. That does not happen with Lightspeed or Sterling Trader (The other platform we own). I have been a trader since 1981. I can tell you that many of us like what we are used to vs what is the best tool for your trading. And, one platform is not the "best" for everyone. Commissions are detailed on our web portal. I'm not sure why I would want that on my trading software. For those with DMA, I can provide granular details for trades including the maker-taker fees. In addition to Lightspeed Trader, we offer other trading software. That is one of the advantages to working with an Introducing Broker; choice. Choice of software and clearing firms. https://www.lightspeed.com/technology/trading-software/ I have clients on Lightspeed Trader, Sterling trader, Silexx OEMS and Realtick. Futures are another story. With regard to the LST API. The API is free but APIs incur non-display fees, because of NYSE, NASDAQ and OPRA newly enforced policies. If you are not getting hit with that yet at your current broker, you will. Sterling Trader has a version with an API without MD leaving the display, so not subject to those fees. You can get your MD somewhere else or for those that don't require it. Give me a call later, if you want to discuss this more.
