I use a tool called Market Delta on Sierra charts with IB free data

I've tried the trial for DAS pro with ST ... very nice platform and fast. I also use TOS (TD Ameritrade). DAS pro has a monthly cost $50 + exchange fees (check with ST), but TOS is free.

YouTube videos for DAS Trader - https://www.youtube.com/user/dastradertv?feature=plcp

I noticed throughout market hours when Tim and the chat room alert about specific bid and ask sizes that they see, it does not show in my Level 2 with SureTrader. After they send out these alerts, others in the chat room chime in that their platform also does not show these bid and ask orders. So I know I am not the only one with a limited Level 2.

I am not certain about suretrader but in TOS there are green, red and grey. I am thinking the blue on your chart is the same as grey on mine. If so I was told that this is b/c they buy and sell where both the same. Ex. you buy 500 shares and I sell 500 shares at the same time. Google volume and what is it actually telling me. Thats my guess.

Same on DAS trader, blue is equilibrium (buy and sell same, 0 move) the handshake between buyers and sellers and a good sign of trend change or a place for future res/sup level

Thank you both for your input!

Since you were so helpful to me previously, I was hoping to ask you a new question! I cannot find the answer online, and the SureTrader reps have not been able to answer my question. I configured a chart in the platform to show the price as a line, and underneath it the volume as bars (like most traders). The volume bars are green (for upward movement), red (for downward movement), and blue. What does the blue bar mean? TYIA!

That is a question I cannot answer I'm afraid, I was wondering about that one myself and was not able to find the answer either

Thanks for your quick response. A couple people sent me feedback as well, and stated that the blue bars may indicate that the buy and sell volume were exactly the same (so no uptrend or downward in that moment).

You are very welcome. I see that, thought that might be the case but was not sure Sir, and I did not want to be telling you the wrong thing
