200 data limit means 200 symbols at a time. but AB can backfill many times, effectively means there is no limit in the no of symbols you should do all your backfilling first, before backtesting. Esignal provides 10 days backfill for tick data, and much longer for other periodicity, So you have choose which timeframe to backtest on.

I "forced backfill" on one of the symbols that didnt have all the data and it filled in the missing data. But there are many more in the portfolio that dont have data. I clicked "Wait for backfill" in the automatic Analysis window. When I reran the backtest I could see it was waiting and backfilling certain symbols, but in the end, many still were missing data.
