Your comment here is ambiguous. It's not clear where you didn't mention how much was invested but you told us how much was left. What percentage of the capital did you suffer as loss so we know what we are dealing with here. Trading is about loss and profit. We don't expect it to always end in profit. Loss is a part of trading.

For Technical Analysis (TA), stick to leading indicators like trendlines and pivot points as against lagging indicators which are often the ones generally used.
