The problem here is, one can only get the resolution down to 1
minute. In this thing I'm coding for someone, he needs indicators
calculated from periodic bars (not ticks). Any signal that
generates a limit order, and the subsequent execution of that order,
must be able to occur inside the same bar.
This is how he trades manually, and I'm trying to automate it for
him. He watches bars form, his indicators update every tick, and
when he sees a signal based on his indicators WHILE THE BAR IS
FORMING, he clicks his mouse to place an order, and often the order
is filled before the bar finishes.
Decent trade-simulation software SHOULD let me perform the same
thing in software, without jumping through a lot of hoops. That's
why I suggested that if indicators can be updated every tick, then
so should signals.
Neither WealthLab nor Tradestation can do this.
Now of course I can jump though hoops; use a tick chart and maintain
the bars internally in an array. But he wants to see the bar chart,
not the tick chart, and see the signals appear on the bar chart.
TS won't let you mix a tick chart and a bar chart in the same
workspace.
Someone else made the suggestion of generating the trades on a tick
chart, and then sending the orders as market orders to a bar chart
using PushPop. This might work.
