Anyone have the Value Chart Indicator for TOS or Esignal?

Guys,

 

What are ThinkorSwim's margins and fees for e-minis?

Have you thought of looking on their website?

Not only did I think of it but I actually had. Have you ever thought that not all that is written is true?

[popstocks 10]

All that is written is true. They have super high margins, and don't let you get intraday margins unless you have I think upwards of 15g in the account, their fees also are higher than usual, you can talk them down a little but fees will still be higher than most. I do not recommend tos for futures, sometimes their data feed slows down to a crawl when things are busy, they also have issues with order cancellation, sometimes you are stuck in an order that hasn't executed and want to cancel but their software has a glitch and it wont allow you to cancel. They are also lacking simple things like, buttons for "Cancel Orders and Exit At Market" or "Reverse" etc - instead it is a big pain to do things like that on the fly. They will tell you otherwise but I have also found that their times for getting filled are slower than others.

Hello popstocks,

 

Thank you for your in-depth explanation that I hoped to get here :-)

 

Given what you wrote TOS seems not to be an option for me then.

[elovemer 10]

... agreed... their charting is decent ... but everything else makes them not competitive....

 

... unless you are trading size.... their comish on futures is among the highest...

$3.50 per mini contract (inclusive of exchange fees) ... from the website....

So, one of the things I like about TOS is that they are constantly improving their product. They do a monthly release, and the enhancements are substantial. They have been adding quite a bit to their futures capabilities including a DOM order screen added in November. It's not perfect, but it's better than sand in your crack.

 

I agree that their margins are very high, and their commish is also high, but for a free platform it's not bad. I have experienced some data problems, but propose that if you are concerned about being locked in trades due to data problems, you should have redundant connections to your home and different providers on the end so you can take the opposite of the trade(s) you have open when one provider has a problem. At least then you can protect yourself from major moves against your position. ALL providers in the path from you to the market are subject to data problems.

 

All that said, I am looking for another trading platform. Ideally it would:

 

- be Mac/Linux compatible (not a requirement, but nice to have)

- have a more flexible order entry system for OCO, brackets, etc.

- have reliable data and great execution speed

- have a well documented indicator / ta language

- be low cost or free

- have reasonable commissions

- have an API (C++ and/or java) for my future robot to talk to

- have low daytrade margin requirements

- and have good tech support

 

If you have suggestions, let me know. I've tried Tradestation, but don't really like a la carte data fees. I've been looking at Infinity now that they have some charting capabilities, but not sure how flexible it is.

 

For now, I'm thinking that I might go with Infinity for execution, but use TOS for charting. Thoughts?

[olie1018 10]

Using Infinity and TOS is a great combo... i use both plus esignal for their efs... TOS recently added coding onto their platform...

I am in the same spot as you. I am looking for a better solution with nearly the same requirements. I have been messing with NinjaTrader and it is ok.

 

I am considering IB as the broker with Ninja for charts and Bracket Trader for DOM/order entry. This solution is nearly free with much lower commission compared to TOS. MB Trading could be done the same way, although I keep reading horrible stories about them. I hate IB's TWS platform but they have a good API and alot of vendor support.

 

Tradestation is on my list as well since the data fees are offset by the lower commissions, but like you I am not a big fan of the software package.

 

I really like Multicharts, but I just can't justify the price at this point. If it had in support for Zen-Fire as well as a trading interface (DOM and Time & Sales) then I might consider springing for it as I would eventually make up the cost in commission savings.

 

Infinity along with Ninja/TOS is also an option I am considering. I just wish the Infinity AT platform was able to show your account details. It doesn't seem like a big deal, but it is to me. Also why doesn't any of the pure futures brokers offer ACH/ETF? I hate having to pay them for wire transfer or take chances waiting on checks in the mail...

 

Ninjatrader will allow me to build my automated trading strategy and then test it against live data for free. Once I am ready to go live then I can pay them to start trading.

 

Tough decisions, as I have gotten spoiled with the TOS interface.

Consider Global Futures, then you will get Multicharts for free. This is a new offer by TSS.

Inifinity says showing such details real-time would consume to much resources (bandwith / server) and would cause the platform slow down.

 

BTW, which platform does show account details real-time?

This eSignal script plots volume in a typical manner with

an underlay of the prorated volume until the end of the

five minute bar. The first plot is the prorated volume and

the second is the actual current volume. This is so the

actual volume plots on top of the prorated volume.

Has anyone created a code for Value Charts on the TOS software? Is it even possible?

It projects what the volume would be at bar close based on how much as occurred so far.

[waveslider 10]

So does think or swim allow you to backtest options strategies? I went to their site and it doesn't look like it.

Does anyone have any recommendations for this? I am looking at Optionvue, haven't found much better...

[popstocks 10]

This will not work in TOS, their code does not allow intrabar resampling (you cannot get it to recalculate every second) it will only calculate when a new bar is made. If you want to gauge volume more closely I suggest using a small size tick chart and watching volume there.
