Scalping the market

Today i had some troubles with Internet connection. So, i went to shop to fund my account (internet funding didn't worked).
At 8-40 i started to look at charts.

3 trades for today:
1. Buy 1,4279 - close 1,4276 = -3
2. Sell 1,4270 - close 1,4277 = -7
3. Sell 1, 4268 - close 1,4272 =-4

Total = -14 (-2R)
I abandoned the rules for today. I've entered third trade, while outcome of second trade was unknown for me and first trade was a loss.
So, if i have a loss and enter second trade i should wait until it closes, before opening third one.
