MQL EA quantity limits for condition tests

[stargate]

Tried using the search function - so if this has been discussed already please just point me in the right direction.

Is there a limit to how many conditions may be tested on the current bar in an EA?

If no limit then does anyone have any practical experience with bogging down a system when using high number of conditions on every timeframe and every pair?

I use a quad core w/ 6Gig ram but my project may be too large so any help would be welcome for info on what limits exist, in the MQL or practical.

Thx
