One should avoid trading when a trader is making continuous loss or in a situation or tie when a trader cannot concentrate on trading.

I trade breakouts but i set multiple entries at certain levels in anticipation of a retracement after the breakout has been established. No retracement, no trade.

The lot size is not applicable in intraday trading. What you need to set in your intraday (up/down) trading is the trading volume, and the timeframe.

A 'Margin Call' occurs when the account's equity to margin requirement reaches 80% or lower. When the account's equity to margin requirement drops to 50%, the account will be stopped out and all positions will be closed in order to avoid any additional losses.

My analysis includes a scan of the pairs on my watch list to see which would qualify for potential profitable trading during the week.
