  1. Updated: 11/19/2018 @ 8:20am (PST) Finally out of the alpha stage and releasing this to the community, I've been using it with success. Because I had to do some musical chairs with memory I made a configuration utility as the script itself is very ugly. This is more of a BETA release for this, so if anyone wants to try this out in SIM and let me know if you have any issues with the configuration sheet or the hotkeys themselves. It's based on the work started by @fjmocke here: https://forums.bearbulltraders.com/topic/469-das-calculate-shares-based-on-account-risk/ . What it is: It's a hotkey command script that can be used to dynamically alter the share total based on: Available Buying Power (capital) Stop Location (Risk) % Account Risk OR Fixed Dollar Amount The script includes purchase power protection and won't send an order that you can not afford, it does this by calculating two factors: A - Shares You Can Afford B - Shares at Risk Parameter (e.g. $25,000 account equity, 1% risk = $250 risk, $250 * a stop distance of .10 = 2500 shares) min{A,B} = 0.5(A + B - | A - B | ) But, why male models? I just told you. /Zoolander reference You'd use this to calculate your share total based on what you're willing to risk. So instead of blindly throwing 500 shares at every setup, you can dynamically alter risked amount based on the per-trade setup. I use it on my StreamDeck (will also release the icon packs soon) with modifiers of 100%, 75%, 50%, and 25%. 100% is the A-Plus setups I see, those I have HIGH confidence in. Alternatively, if a stock has a large spread or is low-float, I may only use the 25% modifier key for those. Instructions for Configuration: Go to this link: BETA: v1.46 https://drive.google.com/file/d/1p1J5sFOXjEE1B9HOkaxtfc3cXSO2fnrV ^^ Requires DAS version or above (current BETA branch as of 11/19/2018) for the physical stop portion to work. If you don't use the physical stop, you don't have to worry about it. v1.2 https://drive.google.com/open?id=1v45q-BJ86oaD3cXi0DAPeLraE2AojQ80 NOTE: Version marked as BETA should be thoroughly tested in SIM to make sure it's doing what you expect it to do. Choose: Either "Download" [Excel Users] or "Add to My Drive" [Sheets Users] On "Setup & Instructions" configure your settings. Account Leverage (default for DAS is 4), this is the margin your broker gives you. Some off-shores give 6. It needs to match what is configured in DAS for proper calculations. Max Account Risk %. This is the maximum percent of equity you're willing to risk on every trade (default is 1%). You can always risk lower (more on that later). % of Total Buying Power. If you don't want to calculate based on the total buying power of 100%, you can set this to a lower percentage (example: 100,000 buying power with 60% here equals $60,000 maximum position size) Route. LIMIT, MARKET, SMRTL. Default is LIMIT. Order Bid/Ask Offset. This is the offset you use when you send the price for order, e.g. "Ask + 0.05" (meaning fill me up to 5 cents above ask) Time in Force. Default: Day+ Default Shares. This is the amount of shares you want to set as the DEFAULT SHARES for all trades (e.g. when you click a Symbol and it loads, this is the share total). You can see why this is here in the technical breakdown section below. Minimum Stop Buffer. This is an offset to the stop distance. If you set this to 0.05, it'll add 5 cents to the stop distance calculation (so if your stop distance is 0.05, it'll be calculated on 0.10). Switch to the "Hotkeys" tab. Choose your preferred style. % Risk of Equity (Dynamic) or Fixed Price (e.g. $150 risk). %Equity Risk: Use the drop down to select what you want the value to be % equity. NOTE: This is a modifier AFTER your account risk maximum %. So if you have 1% account risk, and set this to 50%, your effective account risk is 0.005 --> 0.5%. $ Fixed: Use the drop down to select what you want the value to be for dollar risk. Select "long" or "short" to flip the script's direction. Click the cell that contains the start of the command (E column) and Ctrl + C (copy). Paste it into DAS. It should look like a sample command below. Instructions for Usage: First, you must have "Double Click to Trade" turned on in Chart, Right-Click --> Configure --> Settings --> Double-click to trade. Double click the chart where you want to set a mental stop (it does not place a stop order, you can always put one in after). Hit your configured hotkey. Sample Scripts: LONG: DefShare=BP*0.98; Share=DefShare*0.25* Price * 0.01; Price = Ask - Price + 0.02;SShare = Share / Price; Share = DefShare - SShare; DefShare = DefShare + SShare; SShare = Share; SShare = DefShare - SShare; Share = 0.5 * SShare; TogSShare; ROUTE =LIMIT; Price = Ask + 0.05; TIF=DAY+; BUY=Send; DefShare = 500; SHORT: DefShare=BP*0.98; Share=DefShare*0.25* Price * 0.01; Price = Price - Bid + 0.02;SShare = Share / Price; Share = DefShare - SShare; DefShare = DefShare + SShare; SShare = Share; SShare = DefShare - SShare; Share = 0.5 * SShare; TogSShare; ROUTE =LIMIT; Price = Bid - 0.05; TIF=DAY+; SELL=Send; DefShare = 500; Technical Breakdown: DAS has basic scripting. Montage commands have access to very few read/write variables, basic operations, and only operators of addition, subtraction, division, and multiplication. To do this calculation we need additional operators (min function, and absolute function) and more memory for storage of variables. This command gets around these limitations by using user-writeable areas of memory in the program. Since DAS is written in the C++ language (from what I can tell), it's strict on what can be done in these existing memory locations. The hotkey uses the following items (plus the usual Price -- FLOAT): (Assumptions on Datatypes) DefShare -- INT (Used as a temporary variable for storage) SShare -- Unsigned INT (Behaves like an Unsigned INT in certain situations. Used as a temporary variable for storage) Share -- INT (Used as a temporary variable for storage) With the 3 INT variables, objects are moved around in memory so that we can calculate and compare with our variable limitation (be much easier if we could assign our own). To facilitate the ABS() function, we use a trick --> When a negative value is placed into an Unsigned INT it loses it's sign (thus, it becomes a POSITIVE value in memory). A more detailed technical breakdown (step by step) is located in the Configuration spreadsheet up above. Future Enhancements: If need be, I can make a step-by-step video of this entire process. I have a version that uses an AutoHotKey macro to drop a line at the stop location, I can upload that as well if people want it. ^^ Update, I discontinued this as it was too cumbersome. You had to have two sets of hotkeys for each command. I may someday revisit it if I can build out a configuration tool for it. TLDR: It does the math for you so you can risk a known amount (% or $) based on your per-trade risk position (stop distance). And yes, I'm a bit of a tech nerd. Also, longest post .. ever. Would not read again, 0/5 stars. --- KNOWN ISSUES: %Account Risk gets smaller and smaller when subsequent open positions Reason: No Equity variable, we reverse calculate equity using Buying Power. On subsequent positions, the % (e.g. 1%) calculation will be based on the available buying power and NOT the account equity. Workaround: Precalculate the %risk and use it for the $risk versions. So 1% of $25,000 equity equals $250. SSR rejection on LONG position when scaling out; rejection message (e.g. "Short marketable limit order disable due to SSR!") if using the automatic STOP trigger. Reason: DAS calculates that the position will drop below the open stop order position and reject as this can cause the position to "flip" if it was triggered. Workaround: Have a hotkey to clear the open orders (CXL ALLSYMB), clear it, scale the position (e.g. 25%). Either replace the stop or switch to a mental stop. Alternatively, you can add "CXL ALLSYMB;" to the front of the scale-out hotkeys. You just have to be cognizant to replace the stop order. Equated position size if very small (e.g. 4 or 5 shares when expected is hundreds). Reason: Wrong side was used for the order. E.g. a long hotkey is used when trying to go short. -or- Stop Distance was calculated to be a negative value (clicked too close to current price). Workaround: Be cognizant of the hotkeys used and the stop distance clicked. Clicking too close (a really tight stop) can be very dangerous if you do it inadvertently. TriggerOrder for automatic STOP placement not being sent (no stop order placed). Reason: Montage is not set to a style that doesn't allow TriggerOrder input. Styles not compatible are: Default [DAS's, if you changed it], Basic, OCO, Option, Full Fix: Use a style that is compatible, they are: Stop Order, Detail, Trigger -- I recommended using the "Stop Order" montage style. To change this, right click the montage area around where you'd enter a price and select Style --> Your Choice. --- UPDATES: 10/17/2018 - Added v.1.1 link, you'd need to use the new version to change anything. - General cleanup of the script. Added instructions for the IB issue (discussed in this thread) - NEW FEATURE: Added a new section to the Hotkeys sheet, it will now create a set up for Dynamic Scale-In hotkey commands. You'd use these by setting a scale value (say you want an additional 50% of your current position size). The hotkey will calculate the maximum share you can afford (how much you can afford at the moment) and the scale value, choosing to take the least amount. So if your current position is 1500 shares (@ $50.00) and you want to scale in at 50% your current position, it'd check if you can afford an additional 750 shares, if you can't, it'll buy the maximum you can afford. For this example, you can't afford it (if Buying Power is 100k), so it'd buy roughly $25k worth (500 shares). - CLEANUP: Cleaned up the $Dollar Risk version and removed unnecessary steps. Don't really need to replace yours if they exist, but worth noting. 10/30/2018 - Added @Michael P's suggested fixes for Excel. Configuration tool should now work in both Sheets and Excel. - NOTICE: This was a configuration tool change, no changes were made to the hotkey scripts, so no need to change any existing hotkeys. 11/19/2018 - Shortened some of the commands so we don't hit any hotkey character limit, makes them less readable, but shorter. Couldn't get them low enough to fit the montage buttons though (although removing the portions for the buying power rejection protection would likely do it). - Added a section for SELL/COVER buttons for people who just need to create those. E.g. "Sell 25% position" or "Sell 33% position". - Added @Robert H's stop suggestion. New fields on the setup page for enabling physical stops. If enabled, it'll place a MARKET or LIMIT (settings included) trigger order to go into the market once the initial order is fulfilled, these are placed at the location you double-clicked on the chart. 11/20/2018 - Added a stop-order setting to set an additional buffer for the stop price (for those that want to include or exclude the double-clicked price). - Added conditional formatting to subdue the stop settings that aren't required if you disable sending a physical stop into the market. 12/10/2018 - Added a known issues section to this post and the spreadsheet (for when a new version goes up). 12/12/2018 - Updated known issues section to include the "Montage Style" issue for TriggerOrders. 12/13/2018 - Updated to new version 1.46. Fixed a bug in the Trigger Order script which could cause it to not be interpreted by DAS's command parser on certain user settings. - Added "modifier" extra hotkeys. See instructions next to these on how to use them. - - - Set Stop to Breakeven - Long or Short - Stop Limit or Stop Market (cancels any pending orders for SYMB) - - - Set Stop to Breakeven - Bidirectional - Stop Market (cancels any pending orders for SYMB) - - - Stop - Update Price - Long or Short - Stop Limit or Stop Market (cancels pending orders, double click chart where you want stop before firing hotkey) - - - Stop - Update Price - Bidirectional - Stop Market (cancels pending orders, double click chart where you want stop before firing hotkey) - - - Stop - Update Position - Long or Short - Stop Limit or Stop Market - Replace (requires you double-click the original stop in the Orders window) - - - Stop - Update Position - Bidirectional - Stop Market Orders Only - Replace (requires you double-click the original stop in the Orders window).

    API in DAS

    Hi folks, I am exploring the possibility of using API in DAS to do more efficient and semi-automated trades . I contacted DAS team and they provided me with basic information about their API. I have a decent programming background in Python and FORTRAN. DAS APIs are in C# and text commands in cmd terminal. I have no problem of learning new languages and syntax but before that I need a jump start on how to start the ball rolling (first steps on how to run a simple API either from CMD terminal or executable). DAS provided me with some documentation and example file which are not very useful and clear on how to start to use them (like their other documentation which are not updated from 2006!). I will be happy to share thoese information with anyone with either experience or motivation to explore this topic. Please let me know your thoughts and comments, Thanks
