/*********************************************************************************************** Title: TradeFlow Monitor Indicator for eSignal By: Divergence Software, Inc. Web: http://www.sr-analyst.com ================================================================================================ Dislaimer: For educational purposes only! Obviously, no guarantees whatsoever and use at your own risk. ************************************************************************************************ Project Description: =================== TradeFlow-Monitor gives you several different views of trade volume (bid volume and ask volume) in one indicator. If desired, you can also filter based on trade size. The different views available are: Buying Over Selling ------------------- Displays in histogram format on a per-bar basis. Buying volume is displayed above the zero-line and selling volume is displayed below the zero-line. BuyVol-SellVol PerBar --------------------- Displays in histogram format on a per-bar basis. The net of buying volume minus selling volume is calculated and displayed. BuyVol-SellVol Cumulative ------------------------- Displays in a candlestick format. The net of buying volume minus selling volume is calculated and displayed in a cumulative format. BuyVol% ------- Displays in histogram format on a per-bar basis. The ratio of buying volume to total volume (buying volume plus selling volume) is calculated and displayed as a percentage. SellVol% -------- Displays in histogram format on a per-bar basis. The ratio of selling volume to total volume (buying volume plus selling volume) is calculated and displayed as a percentage. Filtering --------- The default filtering max and min sizes are from 1 to 10000, meaning that any trade with a size of between 1 and 10,000 shares/contracts will be included in the calculations. You can adjust these as needed to, for example, filter out the activity of smaller traders and focus on just what the big traders are doing. Usage Notes: =========== The TradeFlow-Monitor indicator uses data that is available in realtime only and, as such, it provides no historical plot (i.e., it begins operating from the current price bar when it is loaded). IMPORTANT!!!: 1. If the indicator is refreshed or reloaded during the trading day, the plot will be cleared and will begin again from the current price bar. There is no way to restore the plot once the indicator has been refreshed or reloaded. Probably best to load the indicator into its own chart that you won't fiddle with during the trading day. If you are going to experiment with settings (which is a good idea) then do so after-hours using the eSignal Tick Replay feature, which allows you to walk through an entire trading day (tick-by-tick) at up to 200-times faster than 'realtime'. 2. Read #1 again. Recommended usage would be to load it into a lower-interval chart (perhaps a 1-min or 30-second chart or even a tick chart) before the market opens and then let it run. If possible, load the indicator before 9:00am EST and watch the pre-market activity. Indicator Parameters: ==================== Define Trade Size to Monitor: Display: Select the ouput (discussed above) that you would like to see. Select from "Buying Over Selling", "BuyVol-SellVol PerBar", "BuyVol-SellVol Cumulative", "BuyVol%", and "SellVol%". Minimum Trade Size: The smallest trade size (in shares/contracts) for a trade to be considered for purposes of accumulating data. Default is 1. Maximum Trade Size: The largest trade size (in shares/contracts) for a trade to be considered for purposes of accumulating data. Default is 10000. Buying Color: The color to use for plotting the histogram bars that represent buying. Default is green. Selling Color: The color to use for plotting the histogram bars that represent selling. Default is red. Thickness: The plot thickness to use for the histogram. Default is 4. Range is 1-10. Line Type: Select from Solid, Dot, Dash, DashDot, DashDotDot. Default is Solid. Wick Color: Only applies when "BuyVol-SellVol Cumulative" is selected as the display type. Sets the color to use when drawing the wicks. Default is black. Thickness: The plot thickness to use for the wicks. Default is 1. Range is 1-10. Reference Line Color: The color to use for plotting the reference line (zero-line). Default is black. Thickness: The plot thickness to use. Default is 1. Range is 1-10. Line Type: Select from Solid, Dot, Dash, DashDot, DashDotDot. Default is Solid. Logic: Select between "Analyze Volume" and "Analyze Trades". When "Analyze Volume" is selected (the default) the actual trade size is used in all of the calculations. When "Analyze Trades" is selected then a value of 1 is assigned for each trade, regardless of the actual trade size. Note that when "Analyze Trades" is used any filtering that you have specified is still operational and is based on the actual trade sizes. Disclaimer: For educational purposes only!
