RSI DMI MACD help needed

[Leo Ricker]

Hello,

I'm looking for someone who can help me create or find a script in thinkorswim for the following situations:

1) When the RSI with a length of 14 crosses above the RSI with a length of 70
2) When the DMI+ crosses above the DMI-
3) When the MACD Line crosses above the MACD Signal Line

I have seen the standard scripts but they provide different information. For example:

1) The RSI_Scan compares one line versus a % threshold on the graph (Y access 0-100%) but does not scan for the crossover of two RSI lines with different lengths.
2) The DMI_Scan compares each DMI+ and DMI- to a number on the Y access but it does not scan for their crossovers.
3) The MACDHistorgramCrossover scans to identify when it goes from "Negative to Positive" or "Positive to Negative" but it does not scan for a crossover of the MACD line and the MACD Signal Line.

Can someone help me create or find these three scripts.

Regards,

Note: once I have these three scripts, I will need the opposite scripts to confirm a downward trend.
