Tom, re server problems. I think you know better but in case... Disable any passwords to the server, close all but necessary ports, change ssh port, and specifically for you problem use firewall with brute force protection. Check out fail2ban.

Are JL courses worth the money? It depends. For entry lever trader to purchase such course may look like a viable shortcut to learn art of trading. I suppose each of us was there: “if only I study that material really hard...” JL is a very good marketer. He intelligently tells new traders...

Options Playground page will be down for the weekend

Indeed, I misunderstood. Sorry for that. There is no 'export' function in ONE where you can simply export your trade to share with others. There is an import functionality but with limitations. ONE used to have an option to hook up your copy of ONE to your mentor's ONE. I guess you can share...

Olufemi, it looks you are jumping into ONE with both feet. Imo, this is quite important to ask all those questions, even if you don't get all the answers. I believe ONE's team can answer some of those questions for you with great knowledge of the subject. Copying options chain. No, you can't...

There were some problems with last update. Corrected version is on the server now. https://optionsplayground.herokuapp.com/

Tb2018, interesting take. I intend to dive into the concepts you presented when time allows. Here are some 'off the hip' comments, reactions of mine. Important foundation here is a notion that BS model, when applied standard way, can lead a trader to make false decisions. The main thing, in my...

While working on the OPG code I realized something. My focus stayed almost solely on mechanics of the GUI. The goal is to make is as easy as possible to navigate through the tool, to allow user to focus on analysis, not on figuring out what needs to be clicked to get an answer to the question on...

I updated Options Playground tool. For time being link stays the same. There are couple minor and mid-weight improvements/changes. Some of them: - sliders for skew-shape control work a bit different than in previous version - examples of preset skew-shapes and options structures are now...

Michael B, thanks for sharing the experience. I understand broker's position. They care about their exposure and other things, your p&l comes somewhere at the end of the list (if at all). What is very annoying is when we, as traders, meet situation we didn't anticipated. Your warning is...

It didn't happen to me. Few times my orders were placed as Market where I sent them as Limit, but it could be my mistake (likely). What you are saying is horrible. I'd ask about any legal documents that allow them to do such. I guess they don't have clear rules for that. Wonder if that is a...

Tom, probably not the best timing for this post but I have a small suggestion for Aeromir website. I think it would be helpful to have a list of past Round Table meetings somewhere in a single place for browsing. There are good info in many of those videos. The way you present TG1 and other...

Wane, I share the same opinion as, I think, you express through the graph. I have similar one burned into my mind - South See and Newton's story. But. Red line, in prediction part, is only a guess. Blue line can levitate on this level for quite some time or can shoot up again - those are not...

Surely it is bad data. All data I know do have issues. If what you said happens often I'd be worry about using ONE's results blindly. It also depends what you use it for. In general, if this is a rare issue (for what I remember ONE's data weren't that bad, but also I didn't use ONE...

Correct. Single mode operates only with structures on single expiration.

Tb2018, I suppose i didn't answer your question. Sorry for that. I was in the middle of other tasks when answered and wanted this out of my way. I didn't focus on the question but on the answer, if you know what I mean... Back to your question, how _I_ use this app. Nowadays I focus more on...

It runs on server.

Well... There are three approaches I can take to answer your question. I can talk code, mechanics and application. This is not a place to talk about code, imo. Application... this is large topic. All depends on person's knowledge and needs. I can imagine that for some it may be pretty useless...

Hi Tom, thanks for the offer. I surely can use help because I don't have experience in web applications. The one I posted is very basic and Heroku did much for me re setting web environment. If there is interest we can place this app on your server for better user experience. If there is no...

Upps, and here we go... Spelling error in the title. I leave it as is for now but it is called "Options Playground" not "Optios" :)
