Good afternoon. So I've been playing around on MT4 and someone designed an indicator which will tell you when a DI crossover has happened on the actual chart. 

Any possible way this can be coded on TC2000?

It is theoretically possible to create formulas to identify the crossover points of the +DI and -DI to use as Custom PCF % True Indicators on the chart. That said, the formulas are quite complicated. With the exception of very short periods, the resulting formulas are too long and slow to be practical or post in the forums.

PCF for Wilder's Directional Movement DMI-crossovers
PCF for Wilder's DX, and/or a CI for Wilder's ADX
