You need to add the margin needed for up to 20 (or so) trades for each pair ,
For example :
For EUR/USD pair you need to add-
Margin for 0.01 lot=$10 USD + Margin for 0.02
lot=$20 USD + Margin for 0.04 lot=$30 USD +...…. + Margin
for 5.62 lot=$1000 USD=total $10000 USD.
Each broker has different prices.
The only limitation in martingale is the amount of money that you invest, if the trend is against you the EA will open more and more trades until you lose all your money, 20 is just an example, there could be more or less trades.
Not true the EA can open trades also with minimum deposit that is much lower then 10k, use 0.01 lotsize.
There is no limitation.
