You need to have some programming skills to set up ZLT auto trading correctly. One of the problems I remember was that the current bar was generating multiple orders due to price movements. This was solved by some coding in the chart program and adding order id on ZLR so there was only one opened trade at the time. Only market orders were possible, it may be different now. We had TWS started manually early in the morning and Amibroker charts set up to start getting quotes at the time the markets open. The rest was done automatically as Amibroker was programmed to disconnect automatically at desired profit/loss for the day or at specific time before market close.
Frostman must be hard at work on our new software! LOL. Where are you guys? I was thinking about the scanner on this thing. That's a real tool. Frost, can you post a little something on the scanning part?
Frost, Like a watchlist. Let's say I want a list of stocks that gained more than 2 percent they prior day.
For a scanner, say I have a watchlist of 50 stocks and every 5 minutes I would like to totem pole them based on a number of technical indicators each multiplied by a "tuned" weighting factor: like Fast Stoich, Slow Stoich, MACD, and say 5 min bar volume/avg 5 min bar volume. There are others twists and turns, but this would get the methodology started.
It sounds like you have assumed that trade #6 exits before trade #7 enters, i.e., the system only trades a single instrument. However there are lots of traders and lots of systems that trade dozens of instruments at the same time. They have dozens of simultaneous positions. There is no such thing as the last 3 trades.
CoolTrade was developed from the ground up to be a free fully automated point-and-click trading system. It was free for 2 years but now charge $40 a month for the live datafeed, full support and free product upgrades. You can test it with the live simulator before opening an IB account.
