MD80 crew had altitude deviation when they got poor vectors, excessive speed changes, and excessive TA's from the approach controller during vectors for an lda DME runway 30L at stl.

Narrative:
Descent into stl, receiving multiple heading changes, large speed changes, and altitude clrncs, with a 110 degree intercept to lda localizer 30L. Then a clearance to end of runway 30L while receiving multiple questions to look for traffic off right side, deviated from 3500 ft and below, approach said to level and left turn for vector and complied. Came around and landed. Many large speed changes, large heading changes and what we considered unfamiliar clearance with a large intercept angle along with traffic callouts on right side with first officer flying all contributed to the altitude deviation from an overload. No evasive action required.

Title: MD80 CREW HAD ALTDEV WHEN THEY GOT POOR VECTORS, EXCESSIVE SPD CHANGES, AND EXCESSIVE TA'S FROM THE APCH CTLR DURING VECTORS FOR AN LDA DME RWY 30L AT STL.
Narrative: DSCNT INTO STL, RECEIVING MULTIPLE HDG CHANGES, LARGE SPD CHANGES, AND ALT CLRNCS, WITH A 110 DEG INTERCEPT TO LDA LOC 30L. THEN A CLRNC TO END OF RWY 30L WHILE RECEIVING MULTIPLE QUESTIONS TO LOOK FOR TFC OFF R SIDE, DEVIATED FROM 3500 FT AND BELOW, APCH SAID TO LEVEL AND L TURN FOR VECTOR AND COMPLIED. CAME AROUND AND LANDED. MANY LARGE SPD CHANGES, LARGE HDG CHANGES AND WHAT WE CONSIDERED UNFAMILIAR CLRNC WITH A LARGE INTERCEPT ANGLE ALONG WITH TFC CALLOUTS ON R SIDE WITH FO FLYING ALL CONTRIBUTED TO THE ALT DEV FROM AN OVERLOAD. NO EVASIVE ACTION REQUIRED.
