Grid trading?

For the grid machine EA , should I use a cent account cos in the comments in MQL5 , lots of blown accounts have been mentioned ?

When using a grid EA you need to manage your lot sizes to avoid blowing accounts. Grid trading is NOT Martingale if done correctly. Then it's more akin to DCA (Dollar Cost Averaging) where you can effectively move your entry price after you've entered the trade. We are not taking 1 lot, going in for another 1 lot, then another 1 lot, etc. A grid system, again done correctly, would take your total risk (say 1 lot) and divide it up by your max number of grids.

Ex: Say we want to divide 1 lot into 10x 0.1 lot positions on a long trade.

We could enter 0.1 positions at:
