Scanning for Complex conditions that involve indicators in your formula.
There are some basic ones you can create by using indicators direction from charts. But when you venture in to writing complex scans using indicators you will struggle.
If you trying to use any functions like CCI etc in the scan formulas you cannot do that. You have to calculate CCI by writing the definition of CCI from scratch and use them. Here is an
example of how big the formula is to use CCI. As you can see each of those formulas are like a page or two page long.

The same is the issue with many of the formulas such as WMA, ATR etc. No functions provided. One has to write the formula from scratch.
Similarly if you want to do an average of a equation like average range in the last 10 bars, you have to manually calculate by adding 10 bar ranges and diving by 10 as their average function cannot take an equation as an argument.
((H - L) / C1 + (H1 - L1) / C2 + (H2 - L2) / C3 + (H3 - L3) / C4 + (H4 - L4) / C5 + (H5 - L5) / C6 + (H6 - L6) / C7 + (H7 - L7) / C8 + (H8 - L8) / C9 + (H9 - L9) / C10) / 10
I would have expected something like AVG10(h-l) but that since you cannot using functions inside the average function you are out of luck.
There is an open enhancement for this pending for quite sometime but so far no action has been taken.
I have tried unsuccessfully such scans in tc2000 and gave up and for such scans that involves indicators, I go with tradestation. Its little more complex to write there but I am able to successfully write it.
So in summary, for writing quick and dirty scans tc2000 is very good and super fast. Once your complexity increases expect many roadblocks.
