 Using Bookmap's Replay Mode is an extremely powerful feature that can be used to test automated trading strategies, debrief your trading performance, or for practicing your trading since you can trade in the Replay Mode. Let's open up Replay Mode. We'll start by double clicking on the desktop icon. We'll open up Bookmap, and in the Run Options window here you can see that I have the Replay Data available as the choice. Now before I open it up in Replay Mode, let's show how you can record your data files and then replay them back into Replay Mode. So when you start up Bookmap and you choose either the live data trading simulated by Bookmap or live data trading through your brokerage account, real or simulated, you have the options down here to check for record live data. So do that and then you'll be able to record that file, that live file, and then replay it back in Replay Mode. Now you can also note that you have the option here for with live data traded through your brokerage account. You will need the one-click trading add-on feature for this, but when that is selected you also have the option to record your trading activity. So you can just check that box there and it will record the orders. So let's click on Replay Data, we'll select that and we'll open up Bookmap, and it opens up right away in Replay Mode. So let's take a look at the interface here and what's going on. So you can see here that there is a thin gray line that's slowly advancing here. It is loading my replay file data here. You can also see it's very small here, so I'm just going to click to advance it, but there is a blue line that is advancing as well. And this is the actual point that is replaying here in the chart. So you can see here that what I can do is I can hover over this gray line and the tool tip tells me exactly the time and the date here in the file. So I can go exactly to 10 a.m. right here and let's just click right on that. And there I am. You can see that the chart center is here at just at 10 or 10.25, 10 o'clock in 25 seconds is where it actually showed up. So you can see that you can hover over these areas and quickly advance this way. You can also go back in time and click again and go back and revisit some of those areas as well. Now that can also be accomplished here with the VCR type of tools. You have the stop button. You also, let's click play again here. We'll resume. And let's advance this again here. There we go. And you can also set the speed to 1 here or you can fast forward as you can see and go 8 times the market speed or 16 times the market speed, etc. This is a great way for replaying your data for either practicing or very quickly understanding your trading activity and the debriefing. Now you can also go slower than one time speed. You can go at half speed, a quarter speed, and an eighth speed. So those are the settings here for speeding up and slowing down as well as using the advancing here by just clicking forward and backwards. Now there's also another way of inputting the exact time in the file. So you'll note here the data shows on the right hand side here, 14 March 2017. So this is the replayed file from this afternoon's activity. And you can see at what time it is playing here. Now I can also double click on the time here and I can input a specific number or I can advance it here with the arrow keys. And you can see that it's advancing from 20 to 21 to 22, etc. Or I can go back and look exactly at, let's say like 10.04 or I'm sorry, 10.40 there. So you can input them with key values or with using the arrows. Or you can use the arrows on the keyboard as well and quickly go back and forth. And let's go through the pin that you see here in blue. If I have that selected in blue, the tools will always be available here. If I click on the pin, you can see that they're hidden now. But if I hover over the replay file here or the timeline, the toolbar comes right back up. So I'm going to select it. I like to keep it open and utilize the VCR type tools here. Now let's go over loading the files. So you can load different files here. Click on the load feed file. And it brings up the folder from your C drive, your book map folder, and your feeds folder here. And these are all of your recorded feeds. You can sort them by date modified and have the most recent ones pop up to the top. So just select the file there and open it and you'll open your recorded data file. Now you can have different files open up when you open up replay mode. So under settings, you can open up that dropdown and let's come down to replay startup action. So you can choose none if you like and nothing will load when you open up the replay mode. And you'll just have to then click on the load feed file here. Or you can choose load last replayed file. So that would be the last file that you had in replay mode. Or you can choose here, which is the one I have chosen, is load the last used file. And that will be the last used file you had in your live data mode. So the most recent one will pop up immediately in replay data mode. Let's take a look here. You can also choose here to replay your recorded orders if you have that one click trading. Or you can load your orders here if you like as well. You can see you can also export them too.
